I occasionally visit suppliers for work. One is a 5 HR drive and one is 6.5 hrs. I don't live near a major airport, so with the connections it's just a little longer to drive. With all the delays and cancellations, I rent a car and drive to these locations. I would rather control my trip than be stuck drinking expensive airport beer watching my flights getting one delay after another

When I was putting together a circulated set of Canadian Large cents, it wasn't uncommon to see a decent coin ruined like this. Most seemed to be on the Victorian coins and were crudely done ( no pun intended)

Is this your discovery? I'm not a big fan of class IX doubling, but I do think its cool to have a discovery piece slabbed. As other have said, I don't think it's worth it to send in anything else

@VKurtB I did a little research a few years ago using some of the metallurgy sites and and reference books I borrowed from a colleague. Believe it or not, the hardness values of 90% gold is close to 90% silver. That really surprised me. There are other materials properties such as ductility that play a roll as well but I didn't dig that far. So it appears that adding just 10% of Cu and other stuff has a major affect on hardness. I can't recall finding any hardness data on the 75Cu25Ni Alloy for nickels or clad However, .999+ bullion, is definitely softer. Sorry, but I don't have the references. Just have to rely on my memory

Big time beaver coin
Oldhoopster replied to James Zyskowski's topic in Newbie Coin Collecting Questions
Are you a yinzer from western PA? BTW: I put together some Canadian sets about 20-30 years ago. Fun sets to collect, especially the nickels since they fit into your topical collection. I know you're on the other sites and probably saw the member who has a lot of beaver related items from the Pacific Northwest -
It's not a brothel token. Just a coin that someone decided to damage. Collect long enough and you'll come across US and Canadian large cents type of engraving. A coin like this is considered to be damaged and the vulgar engraving reduces any collector value significantly. In addition, it has environmental damage from being buried. It's an interesting metal detecting find, but any collector interest is significantly reduced. Sorry

I never felt there was much point in debating the cause if PMD. Just want to point out that the editors of error-ref (Mike Diamond, Fred Weinberg, Jon Sullivan, et al) felt it was significant enough to include a section explaining it in the Non-Error section It could have occurred in anything where the coin is frequently tumbled, pump, rock tumbler without grinding media, etc. Dryer coin seems to have become the generic term for any sort of tumbling PMD

Under Weight 2007-D Washington $
Oldhoopster replied to tj96's topic in US, World, and Ancient Coins
It seems like it could be a missing clad layer based on the weight and some areas of striking weakness, but I would expect more weakness. I can't tell from the edge pics if there are 2 layers (missing clad) or 3 (normal). I'm leaning towards missing clad layer, but cannot say for certain -
1793 North Wales Halfpenny Token
Oldhoopster replied to JKN58's topic in US, World, and Ancient Coins
It's a Provincial Conder token named after James Conder, the person who first catalogued them. The D&H is the reference number from the book by Dalton and Hamer.- 3 replies

As @VKurtBsaid, opening a second account on CT is an automatic ban. That was the reason you were bounced.

You were pushing this coin for months on the other site, even after bona fide experts, who handled authentic 64SMS for auction companies said you don't have one. Weren't you advised to send it in for authentication if you disagreed with the opinions? Please do not turn this into another thread were you add a few additional pics every month to get a bump and keep trolling along. Send it in for the only opinion that matters, the TPG The host of this chat board has a number of expert graders and authenticators who would be more than happy to certify your coin. Don't mess around with the great unwashed masses of the chat board denizens, go right to the experts. Send it in. Now

1982 Rim Restricted Design Duplication?
Oldhoopster replied to KarenHolcomb's topic in Newbie Coin Collecting Questions
Agree with @Coinbuf. Notice on the error-ref pics how the letters on the rim match the letters on the coin. Yours shows letters from some other location. That can't happen for this type of error unless you saw other features that would indicate the coin rotated, such as double striking on the opposite side. Yours doesn't show that. You have a vise job PMD https://www.error-ref.com/rim-restricted-second-strikes/ -
1979 Lincoln Cent - COUNTERFEIT OR REAL??
Oldhoopster replied to investinrehabs's topic in Newbie Coin Collecting Questions
Electroplating was done as an experiment in many HS chemistry classes. Nothing better than a hands on experiment that demonstrates an important concept. Plus the student gets to take their experiment home Could also be a set up piece or QC check for a small plating operation. We'll never know for certain, but you can be certain that it didn't occur at the mint. -

If interested, Dealers will pay $1.00 - $1.50 per roll (2-3 cents each) for circulated wheat cents. -
1979 Lincoln Cent - COUNTERFEIT OR REAL??
Oldhoopster replied to investinrehabs's topic in Newbie Coin Collecting Questions
It's nickel plated. A 70% Ni 30% Cu XRF compositional analysis is entirely consistent of a nickel plated piece. XRF can penetrate 100 microns or more below the surface, which is below a typical plating thickness. For example, the thickness of the Cu plating on a Lincoln cent is approx. 8 microns. So the XRF is primarily reading the Ni plating along with some of the Cu cent underneath Sorry to say, but your coin is a regular cent that was plated after it left the mint. Nothing more -
I have a small collection of classic commems and love them. However, I only have coins of which I like the topic or history of the event, such as Grant, Gettysburg, Antietam, and Stone Mountain (nice civil war subset). IMO, if you like the topic, classic commems can make a nice, small collection.

I've used quite a bit of XRF and other analytical data doing project work over the years. I haven't run the equipment in over 30 years, but have used both internal research departments and outside labs, but am not up on equipment costs. Usually you'll have a trained tech running the equipment and compiling the data. The benefit of lab equipment is the better precision, resolution, and consistency of the trace elements. A lot of this comes down to the algorithm software. The signal from the primary materials many times overlap the trace elements, making them hard to to identify. That's why you need good software. The handheld units are generally set up for measuring the bulk material without worrying about trace elements, which keeps the costs lower. Generally precious metal buyers aren't worried about how much trace antimony or zirconium are in a sample. I don't think that answers your specific question, but hopefully gives you an idea of why lab grade equipment is needed

If you like the signatures, go ahead and collect them. If you want to buy them because you think they'll be more valuable with the signatures, I think you have some good feedback here. Maybe a small premium if you can find the right buyer, maybe bigger if you get lucky, but probably the same value as a standard slab to most collectors and dealers

If you're into the hobby for collecting/investing then I agree, but if your interesting is the history behind the coins, how/why they were made, how they moved through commerce, and how contemporary people used them for daily transactions, then research like this is fantastic. The cost and access to samples could be a formidable barrier, however. But it can't hurt to hope. There are some studies tracing ancient coins to mine sources that I found very interesting (I don't have the sources handy. Sorry)
