Was This Once A Copper Coin?

No idea but it looks pretty interesting. Hopefully someone will be able to I.d. it.

Definitely a Byzantine trachy! Something like this:


But hopefully, someone more schooled in these will be able to narrow down the type.

As for what it is made form, I assume it looks coppery. It is therefore a trachy, made of billon - a very debased silver.

Definitely worth more than 10 cents - even unidentified and unidentifiable trachys should sell for a few dollars, at least.

Sheesh, that thing looks like a petroglyph put on a horseshoe crab. You guys are good.

I was amazed to find out what it is.
I check through their junk bin once a week if I can, and I think they are amused that I can tell what they've bought and tossed into the bin between my visits even though the bin is filled with a bazillion (rough estimate) of duplicate modern coins.
I think they are also tossing in things that didn't sell after being in their sale-price boxes, maybe just to hear me and my counterparts gasp in amazement when we discover them.
It is harder to see the marks on this trachy without strong light and a good magnifier, so maybe they figured it wouldn't sell as well as something else that now uses the shelf space.
