It's absolutely impossible for the coin you posted to have been minted that way. If you research the minting process, you'll easily see why this...
You need to accurately weigh it to determine if it's zinc or copper. Denver made over 6 BILLION CENTS in 1982 and only one copper small date has...
The 69DDO is easy to to recognize. If you aren't sure and have to ask, then you don't have it. Your coin isn't close. I don't have the link handy,...
Still cool finds. Even though they aren't worth much I keep them
Saw someone who collected 1 coin from every country from his birth year. That seemed like a manageable take on the every country theme
you're right about it not being an error. It's most likely environmental damage and probably related to whatever crud is on the reverse and stuck...
I have one of the cancelled Olympic commem died I purchased directly from the mint in the mid 90s. I think the price was $59
Smart move, in my opinion
Waiting in breathless anticipation for your Friday reveal. Spoiler alert: Don't cheat and read the rest of this post (or the first few posts)....
The parallel lines are cut marks. Something like a metal shearing tool could leave a mark like this. Obviously, the industrial tables (below) are...
Thanks @H8_modern. Great buy on the books. IMO, nothing better than finding old numismatic references. I have over 250 different reference...
Most (all?) Early notes where hand signed so if the signatures and serial numbers are printed and not handwritten, there is a good chance it is...
Yeah, that's the Stony Brook Univ paper. The research was corporate funded to support a change in the ASTM procedure for testing copper used in...
Probably a good thing for you to avoid using acetone. If you're having numerous coins change color at different times, it sounds like you're...
Even though 4 zeros have a minimal (if any) premium I save them if they are in in good condition. If yours was a $1, I would keep it. But I...
Wish I could give this multiple likes.
^^^^ Agree Great Britain Farthing, Half Penny, or Penny (depending on the size). Probably minted 1860-1894. It has too much wear and damage to...
A little tricky but it looks like there's some raised/displaced metal on the rim and that would indicate damage.
Correct IDB. The 3 took a hit at some point. Notice how it is thinner than normal (plus look at the hits on the other numbers)
Separate names with a comma.
