We saved miles at the corner saloon, where lots of people don't collect their miles and leave them at the bar. Got a set and used it for home poker set.

The "service" that formerly did the laundry had a light finger delivery guy who stole those and my home play set. (Wisconsin obsoletes of the common variety) When confronted he returned part of the Marlboro set and none of mine. (hope he tries to sell them someday, or take them back to a casino, I know the chips well)

Meanwhile a patron traded his set, in the box for six free drink chips. (he drinks Absolute on the rocks)

I found another set at rummage for $10.

eBay may be one source and saving miles another, but the chips aren't unusual or rare.

Personal estimate, a complete set, in the box = $10 - $20 value.
