Just throwing out some rough ideas since I have no idea what it is. It looks like it was made to be engraved on one side. I think it looks like...
Regarding the 1921 Peace, I believe that sending it for slabbing is a waste of money. You said the coin was a little worn. The Heritage price...
My 1991 Third Edition VAM book only lists 2 varieties. Yours must be VAM-1 because it doesn't look like PEACE is doubled. I think it grades...
Yeah, but he has some nice pics
FWIW, Pd and Rh are used in the catalyst system on the catalytic converter in your car
Have some ancients from the "Great Uncleaned" days of the early-mid 2000's. Dumped most of the bad ones on ebay years ago, but hung on to a bunch...

Can't say for certain due to the pic, but it looks like the letter are pressed into the rim and not raised. If they are reversed (mirror image),...
The ingot was rolled between the 1-2 O'clock position and 7-8 O'clock position (I believe they roll in both directions). During rolling, the...

Assuming the color on your pic reasonably matches the coin, it looks like it was plated after it left the mint. There are lots of posts about...
It was etched. Acid etching removes the surface microstructure and then begins to selectively remove the metal in the grains along crystal...
Wow, you can see how the of grains have elongated during the rolling process.
I do this with lower value coins and have not had any issues with PVC residue. As long as the mylar window is intact, you shouldn't have a...
I agree that the ridge through the letters on 1986 and 2004 that you posted are are due to worn dies. However, 1985 cent in the OP is NOT due to...
Notice how all of the devices are spread. Copper is a relatively soft metal. Repeated impacts will cause the metal to "smash and spread out". I...
When you see "doubling" on both the date AND mm, that's a pretty good indication that it's machine doubling. [sometime in the 90's, the mint...
Paddyman98 was holding it when responding to a "Double Die" question.
