Thanks SPP,I see you're next in line for the milestone,congrats in advance.
@ pennyman007 coca-cola coin is just a name,doesn't imply that it was actually used for this coin,some say cola will do this,others say not,I haven't tried so I can't confirm or deny the results

High school lab. HCl would be good enough to yield this result.

Just curious! I haven't had a lot of experience with acid and metal but the experience I have had blackened or at least darkened the metal and also leaves it pitted or is there an acid that doesn't have that effect? I've never really tried acid on copper!

Here's my only Dryer Coin. Notice the rim is raised far above the coin - it can actually hold a penny on both sides pretty well.  |

I had never seen one before. I mistakenly thought all that rolling & tumbling would have knocked metal off the coin causing it to diminish in size. I can see I was wrong. I'm still unsure of what to tag my cent or whether to forget about it and just toss it out.

Well either way its a learning experience. Videos about minting coins are on youtube I understood things better after watching a bunch of them a few months ago.

bobberbear,nitric acid will quickly do the trick to turn a penny into exactly what you have.
Do not try it yourself,it is very dangerous.
You can tag your coin as "acid etched".

I'm told there are others that will do the trick but nitric acid is quick,and entertaining.
