I was the only bidder on this coin and it was cheap, but in-hand it seems odd so maybe that's why. There is a strange sheen to it like it had been cleaned and/or somehow lightly waxed. As a newcomer I don't know what I am looking at as far as condition. It's hard to quite photograph what I mean but perhaps experienced eyes will see what I mean. Thank you in advance as always!
Here is a page with several examples. http://augustuscoins.com/ed/ricix/type5i.html The coin is genuine, but it looks like it has had something smeared on it. It could be wax or even fingernail polish.
some waxes are more resistant than others, start with acetone and a toothbrush and then, if no results, try xylene.
If you don't like the wax coating, just toss it in either vinegar or lye for a few minutes and it should take all the wax right off. Beware: wax is often applied to hide something.
I think for a $7 ancient I'm not going to worry about it other than the desire to understand what I am looking at. Thank you all again.
Uh...think I would try acetone and xylene before this. Both vinegar or lye can cause surface changes to metals.
