Actually, buying some uncleaned Imperial Romans might not be such a bad idea. When I started purchasing lots of 5, 10,and 15, I actually made the judgemental error of selling a few (pretty good ones too) before I was up to speed on their value's more-or-less. Now, I wish I hadn't done it. It just wasn't worth the $10 or $20 I got for some really neat coins I believe that coin is based upon a comet which was seen in the sky after Caeser was killed. Bone
