GoldFinger1969, I considered that too. All boxes are in ogp, within ogp boxes, with dessicant packs, but there is the fact that all wood has outgassing chemicals, such as the cabinets they are in, the desk in the room, etc. however even though the sets are not hermetically sealed, and only have plates and cardboard ogp), it seems like being protected in a closed space with dessicant is far better than them just sitting in a drawer or on a shelf or in an old shoebox. seems to me that the chance of damage is very remote, however I am considering changing that.

Don’t I know it! All in spent about $1,300 pgcs values state about 2,400 believe it or not the hardest one to obtain was the 2020 set, with the “w” proof nickel

Darn I might have to buy these now. Coinbuf, would just cardboard proof set boxes suffice or would these intercept shield boxes be preferable?

In reading about “outgassing” no offense VkurtB, but I did find this article on line at a collectors site. Maybe there is merit to what Coinbuf has said. So how , would you suggest I Store them humidity free? From the Art Conservation Center at the University of Denver's Judy Greenfield, Conservator of Objects - "Building a Better Case":"True African mahogany is reported to be one of the least corrosive woods, but it's expensive and difficult to procure, and other mahoganies sold as substitutes are corrosive" (Hatchfield). Additionally, mahogany is resistant to termite attack. There is disagreement over the benefits of seasoned wood. Kiln-drying (seasoning) wood helps break down and drive off some inherent acids, though it may depress the wood's RH-buffering ability (Miles). But Werner cites the Department of Industry's statement that "[seasoning] wood...accelerates the production of free acetic acid and formic acid. Most of the acid, however, remains in the wood." So, even if you are lucky and your cabinet is actually made out of true African Mahogany it is still only a lesser evil. While Mahogany is much more stable than red oak, particularly dimensionally which I imagine would play a role in cabinet making, none of this this alters the fact that wood is factually not the best choice of material in which to store coins. I continue to quote from Art Conservation Center at the University of Denver, and this information is specifically in regard to display/storage cases - not so terribly removed from coin storage. And remember, display cases in museums are often temporary and yet these matters are considered. Many of the displayed items cited in the article were metal"Although some woods are worse than others, all emit a variety of acids, aldehydes and other lignocellulosic degradation products." (Miles). Wood emits mostly acetic acid; formic acid is produced at 1/10th the amount of acetic acid(Blackshaw). Moisture hydrolyzes acetyl groups in the hemicellulose (a form of cellulose, the "building block" of wood) to produce acetic acid. Elevated temperatures appear to foster acetic acid production (Werner)." I don't know what to make of the claims about sanded mahogany - it is also agreed among conservators that all woods must have a barrier between the wood and the display case interior. "No wood can ever be completely sealed to stop emission of organic compounds, though sealants can impede emission." At least one case I saw made by Mr. Nichols appears to have the coins "exposed" to the inside finish, which IMHO should not be inside the case at all. You don't need physical contact for outgassing problems, and we know PCGS slabs are not "sealed" and plastic is gas permeable anyway. Also, the PCGS boxes are "cherry wood finish and are lined with black felt" - I don't have any idea what wood is used, what adhesives, what finish (oil /Varathane?) or what fabric. To me, once closed, the environment in a wood box is concentrated - and the wood just sits there outgassing with the adhesives and finish, waiting to absorb large qualtities of water...now if the box is in a safe.....Someone mentioned Varathane - "Even after 18 months' drying time, oleoresinous (oil) paints corroded lead in an experiment cited by Miles. As oil products dry, they undergo oxidative degradation which yields volatile organic acids, aldehydes and carbon dioxide (Miles). Oleo-resinous products include oil-modified paints and varnishes, one-component polyurethane varnishes (e.g., Varathane), alkyd paints, epoxy ester paints, aluminum paints, silicone paints and most varnishes (Miles)."The information just goes on and on...and on - ESPECIALLY about the harmful glues and adhesives that might be used in construction (perhaps more important than the wood and as important as the finish), the fabrics - fabric should not be used where humidity is not controlled (someone mentioned a tarnish retardant cloth - these can be bad - as can certain dyed felts etc.!)...all can be injurious, and usually are unless care is taken. All I am saying is that wood in not an ideal choice, or even second choice for long term coin storage. Yes, this data is about storage/display cases in museums, but most of the problems above seem are mainly influenced by humidity and temperature - variables found in every deposit box and safe. And those are concentrated environments, more than the cases in the above discussion.

Coinbuf, is there any scientific proof that mahogany humidor boxes with desiccant packs in each can cause problems? Bill

In February, 2022,I owned about a half a dozen PROOF SETS. I began a quest to obtain the early ones so started at 1955. Throughout 2022, I sort of made it a personal goal to obtain as many proof sets as I could. I am happy to report that I have completed my quest! I now have every production proof coin from the San Francisco mint since 1955! including SMS sets, now over 67 sets. just think, Every Proof penny, nickel, dime, penny, half dollar and golden dollar that ever was minted at the SF mint! of course special issues like the W penny and the Jefferson nickel are included. Kennedy half dollars State quarters ATB quarters Sacs, Presidential, and Innovation dollars special issues like the RP Kennedy quite proud I am. I don’t know how many people have done this, but now that I have, I ask What would you do? crack them all out and put together sets of denomination, types? keep them for heirs? send them in as sets for grading (gasp)? sell them as a complete set? just asking your opinions thank you in advance.

LemE saw this on Ebay

JP, you might find a can like that under your kitchen, not my house which was built in 1995 new by us.

Very nice 👍 these three alone nearly $9,000 according to PCGS

Nice group but you are not likely to find any bargains in those. If you are going to pay high retail why not just buy graded examples.

Jimbo I have reported it to Ebay thank you

Environmental damage can mean the coin was contaminated by external means like being buried. Are you hung up on getting a graded coin? This coin seems to carry a fair value I found a raw coin on EBay that looks promising, perhaps you could get it graded yourself.

Already on the notification list!

I have a rule with coins. If I can’t read em I don’t buyem

It called a British HIND ship.

I got a JP kinda deal today. 1967 British Half Penny, $2.00 free shipping.

No and don’t call me Shirley

I have a number of duplicate proof sets for sale. , 1989, 1990, and 1998. Message me with you best offer if interested.

Australia New South Wales 15 pence HOME RESEARCH AND COLLECTIONS SIGNIFICANT COLLECTIONS SIR WILLIAM DIXSON NUMISMATIC COLLECTION Sir William Dixson numismatic collection Over the course of his lifetime the wealthy Sydney businessman Sir William Dixson (1870–1952) amassed one of the world’s most extensive Australiana collections. The collection included paintings, rare books, maps, manuscripts and one of the finest numismatic collections in Australia. (Numismatics is the study or collection of coins, banknotes and medals.) There are over 7800 coins, notes and tokens in the collection and together they are a highly significant and valuable collection for any researcher interested in Australia’s colonial past. One of the most significant coins collected by Dixson is the Holey Dollar. In the early years of the colony a lack of currency meant that most of Sydney’s financial dealings were made by bartering rum, corn and other produce. In 1812 Governor Macquarie imported 40,000 Spanish dollars to provide local currency. The centre was cut out of the coin to double the number of available coins. The outer ring became known as the ‘holey dollar’, and the centre was called the ‘dump’. The Dixson collection includes 60 holey dollars and only 300 are known to exist globally. The first officially minted Australian coins were issued in the wake of the influx of wealth caused by the discovery of gold. The Dixson collection includes many of these early coins and other examples of first issue coins minted in Australia, commemorative coins, original dies and even examples of forgeries. One of the rarer examples is a restrike of the 1852 Adelaide ‘Square Pound’, it is one of only 12 made from the original dies. The collection also contains many examples of rare, locally produced tokens used by Australian businesses for their daily transactions including the first Australian-made tokens issued by Peek and Campbell, who had them made locally by JC Thornthwaite in 1852. It also holds examples of 1823 tokens imported by the Hobart firm, Macintosh and Degraves, for its Cascade Sawmill business. Almost as rare are the examples of the 1849 tokens by Annand, Smith & Co, family grocers in Melbourne. One reason Australian tokens are so collectable is because they were made illegal in 1868 and were withdrawn from circulation. The absence of local currency in the colony’s early years also led to the extensive use of redeemable promissory notes in lieu of money. These were produced by local businesses but were also issued by the government administrators. Many were produced on flimsy bits of paper which could fall apart before the owner was able to exchange them for coins or goods — hence few have survived. Those in the Dixson collection now provide valuable insights into the financial and social fabric of early Sydney and the later settlements. The Australian bank cheques, and promissory notes in Dixson’s collection cover a broad time period and significant events in Australia’s past. Examples include early currency notes payable in Spanish dollars, a Wesleyan Methodist Missionary Society Bill of Exchange from 1826, paper money issued during the Australian occupation of German New Guinea in 1914; and money printed during the Japanese occupation of Malaya in World War Two. Given the central role which money played in the early cultural history of Australia it provides researchers with a unique and palpable window into Australian life in the wake of European settlement.  On his death in 1952 Dixson bequeathed his numismatic collection to the Library along with the rest of his extensive collection. A detailed listing of the Dixson numismatic collection is available in our online catalogue and many of the coins, tokens and notes have been digitised.

Love those Brittania’s i have several, King George 4. King George 6, Victoria, Elizabeth coronation, marriage, Prince Charles and Diana, Churchill and a lot more. None of them graded but self slabbed examples. Your wife should love them. also have an extensive Canadian collection with a whole lot of Kings and Queens that she would also like. Careful you just might turn her into a collector.

I was checking eBay sold items and it looks like the raw sets are going about $70-$100, while the graded 70 sets are several hundred or more. Even if they came back as a 68 or 69 this might be the time to get these graded as they are the only ones edge incused. IMHO I would send them in.
