That observation is correct for the first paragraph in Pete's posting, Jill, but not for the second.

1. Gamblers must itemize their deductions to offset gambling losses against gambling wins.

2. However, as a collector, you report chip/token sales on Schedule D (Capital Gains and Losses) and so offset your sales price with your purchase price plus any commission you paid. If you keep your collectible for a year and a day or more, you also get the benefit of Long Term Capital Gain tax rates on any gain.
Dealers can't do this as their sales are part of their business.

I'm sure JimP will have more to add to this subject.
