Believe it or not some of the Julio Claudians were very expensive and hard to find way back in the stone age. Asses of Claudius go for about the same and often less than they did in the 80's. Nice Folli are about the same too. Since the fall of the 'east bloc' the coins of the Balkan cities (Viminacium Stobi etc) have dropped through the floor. We used to pay around $70-100 for the Roman Colonial issues in VF, Now they are $25. One thing for sure though the Constantines which I tired of and bought back in the 'old' stone age when the President was named Carter ..... well we used to buy them in VF/EF for a couple of bucks apiece ! I thought I made a killing when I sold them off for $5 apiece about 5 years later.
