That could also explain why my coin had an old tag that read "Ptolemy II."
I asked this question about a different coin of Postumus a few weeks ago. It seems that coins originally thought to have come from Cologne are now...
Have you checked the web site that TIF referred me too? http://ptolemybronze.com/ptolemy_series.html The hemidrachms tend to have a club or...
Thanks TIF. You are right, my coin does look a lot like your. Do you know the mint city? Is it Alexandria?
I, too, think $700 is too high, but it is a nice specimen. I don't think the photo does it justice. But, yeah, look around for other examples...
[ATTACH] I just picked this up at the Westchester Coin Show. The only information that came with it was "Ptolemy II." The coin is 38 mm and...

It can take a while--15, 20 minutes even--for the coin to start bubbling. Here's a site I found with some information:...
It doesn't look as if any damage has been done to it, other than starting out pretty worn and then spending the next 1600+ years in the ground.
I haven't dealt with nobleromancoins for years, but back in the day they were honest and had nice quality coins.
I've heard this before. Actually, I think a hot glue gun works even better. But I haven't tried it so I can't vouch for the method.
I used to sell uncleaned coins many, many years ago. Here's a copy, edited slightly to remove all the out-of-date links, of the note that I used...
You can remove the patina from the raised area using a little dish-washing soap and a green, Scotch scouring pad. (Off brands generally don't...
