I specifically did not go after Silver sets. Only have 1, the 2011 plus the pre 1964 sets, and the 40% sets through 1970. Nice to know someone who has done this. Since you quit them in 2021, why not catch up?

That’s ok, I have my registered birth set all NGC. And I don’t have the Booker T.

Ya I know a fella that has a 1954 set in OGP box for $130 maybe I’ll do a few more to get to my birth year 1947 (omg) you that old?

Yea good luck on that!

Thanks Coinbuf, I may just make sure they are in and continue to be in a relatively dry environment with dessicant packs in each box. Since the copper in these sets is really nothing outstanding, if they reacted, would it just be toning, and doesn’t that help value? I’m really not sure what I’ll do with All if them yet, but if I get a chance to sell the whole lot, I might. For now, goal accomplished , on the next big thing. At the very least, I have acquired over 550 proof coins and that in and of itself is an accomplishment. B

Just the challenge, and because I do like them all.

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
