I just found this today and the first thing I thought of was a large cent. Then I thought it might be a electrical box knockout. But when you drop it on a hard surface like a table it gives off a coin sound. Those knockouts usually have a dead sounding thud when you drop them. I put it under my microscope and can't see anything obvious. The photos are both sides with the quarter just for reference. I was wondering if electrolosys would work...I never tried it before. I have 2 power supplies here 12V and 24V and was looking for a "how to" sticky post on that. Can anyone point me to a good tutorial on electrolosys with a power supply? Any other ideas? Thanks.
