.... or maybe the following:

1. 3 years of my selling 12,000 chips and tracking all of them on spreadsheets ...... complete with buyers names, dates, percentages, sales price, book values, etc etc etc ........

2. An additional 3 years of overall general ebay sales by a good friend that tracks them for a living ............

Other than that, I guess I am just whistling Dixie .... ????
