Well Lloyd, I weighed this coin again and make a correction. It weighs 6.0 gm at 17mm which is
still below the
standard of 8.5 - 8.6 gm. That's OK by me if it's a
fake because I paid very little for it. I bought this coin as well as the other 3
Byzantine gold coins (which are listed) at the same
auction less than 2 weeks ago. I've not been told they are
fakes but I'm waiting for you to tell me that they are however, lol. The
Philip I you mention was purchased by me 5 years ago on
eBay as stated in the comments of my listing.
Still, more than 3/4 of all the coins I listed are authentic so I wouldn't say I've 'been pretty unlucky so far' if I were you. I'm content for having made purchases with absolutely no knowledge of
ancient coins. EZ
