Those deposits look like accumulations of cuprite, Cu₂O, an oxide of copper. They are extremely hard to remove and I don't recommend even trying;...
Thank you. It was possible back then to cherry pick these coins, there were so many of them. The dealer charged at premium, which was quite...
Yes, that design has been used in currency as well. Thank you for mentioning that and posting some nice examples.
Ever since the first minting of this magnificent gold coin, the 50 gold pesos, with its beautiful obverse and reverse designs, have graced...
I took an image from the current HJB BB Sale 217 and used the haze removal tool in Photoshop. The one on the left is the original and the one on...
Here's my latest HJB pickup, from BB Sale 216. My Roman provincial collection is a real hodgepodge. Given the extensive nature of the coin types...
That's really your call. Some collectors and other folks will pay a premium for a slabbed coin, basically because it has been "vetted" by NGC or...

Very nice anonymous folles in this thread. Here's an "old timer" that came from Stephen Huston back in the early 1990s. Romanus IV, 1068-71....
Beautiful bronzes! Here are three from the Carmona Collection, all purchased from Roma: 1. Galba sestertius. I've been looking for an...
Nice coins! This is a relatively new acquisition. While quite often available, this sestertius of Faustina II has a fairly uniform, hard...
Interesting questions. The most that I ever paid for a coin was $26,000 for the Segovia 50 reales, 1635 R, back in 1997. I guess things were...
Definitely an 8 reales from Lima, Peru. Chop marks can be a collecting subspecialty in itself. Some coins have so many chop marks and cuts, that...
