46/339 R1 in copper
Gordian III Antoninianus. I think it may be RIC 15 Sear-8632 (lots of TR P II reverses with standing deities holding stuff). Not up on current...
I think you mean ferromagnetic. Nickel and cobalt are magnetic but not ferrous.
If you have the opportunity in your area, I would strongly encourage you to join a local coin club. You'll meet lots of friendly, helpful people...
Generally, birthday or "date" notes don't carry any numismatic premium. You may be able to sell it for a small premium if you can find someone...
I'll take the 82-D small date in bronze, please :)
The no S coins were minted with special dies as Proofs and issued in official government sets. All Proof coins since 1968 (with a few special...
The picture looks like the letters and portrait are incuse and that's what I would expect from a brockage error. If the OP can provide a weight...
As others have said, it's only worth about a cup of coffee, but still a really cool find.
It looks like it could be a brockage error. An accurate weight and diameter would help. You may have something good but don't get your hopes up...
I agree that they aren't adjustment marks (Question for the EAC guys - Did the early mint even make weight adjustments to copper??). I think...
Assuming you're asking about the mark under the date, it appears to be a corrosion spot or plating bubble. There is also corrosion on the rim at...
Could be that the die wasn't annealed properly leaving softer areas that have worn as the planchet metal flows or harder areas that got undercut,...
Not a total loss. You did a nice job on the pics
It looks like a broadstruck error. The planchet doesn't look like it's silver from your pics. To be certain if you have an accurate scale, the...
I don't think you can tell how far the stain penetrates without cutting into the coin. The environmental reactions are on the surface and at...
Sorry, but it's just your standard, everyday, run of the mill environmental damage. Copper is a very reactive metal and there is a lot of nasty...
I don't think a 23mm planchent is going to fit into a smaller cavity used to strike a 21.2mm Nickel. It would have to be a broadstuck error as...
You can think of the dollar coin, like the dime, quarter and half dollar, as a sandwich of metal. The clad coins contain an inner core and...
Learned something today. It always seems to happen to me when I start to think I know a lot about numismatics. :happy:
