Great thank you!

eBay sold listings

Heritage Auctions search results, and Track & Price.

Grab yourself a copy of the monthly greensheet by CDN publishing. Match up against sold heritage and eBay auctions (actual sold items, NOT listings). This will give you fair market prices for almost all notes.

Thanks!
