I was looking at a auction for a MoneyBucks Handbook can't say I've heard of i, but some of the TPG's use it for reference and my question is, is this any good as far as Jefferson nickels go or would it be a waste of $? I'm thinking of picking up a copy? Also, the last 2 days I've seen RPM's listed with a VP number. These where listed on Teletrade and ebay. I have not seen these listed before and was wondering what reference material these refer to. Thanks for any info.
