So are you saying the
rarity of most coins are based on the number that come up for sale. The fewer for sale the higher the rareity. I understand supply and demand I have a major in economics and am a CPA in accounting. Collecting is a hobby. The coin was not sold as
Diadumenian an
Macrinus but as
Caracalla and
Domna. I knew better but I
still could not find the coin until I was advised on this site and that is why I love it. So much knowledge. Just because I have been collecting for 30yrs. does not make me an expert. Plus I do not specialize in any
area. But I love coins and when I see one for sale miss IDed and not to expensive I buy it. But if any one would like to give me a better idea on how they come up with the number in circulation at anytime please feel free. Regardless of
rarity the value of any coin is what you can get for it at the time it goes up for sale. I may get lucky I may break even or even lose but I don't buy them as an investment. But they have become a large
part of my investments, I assume it is less risky then stocks and collectors can go carzy over a coin they want for their
collections. I know I have over paid many times just cought up in the rush. I try to pay about 20 to 40 percent of the listed
price so that when I sell them I will at least break even. It is now listed on
wildwinds and I am as prod as a new parent.
