I did that last year with five chips, five identical descriptions, all listed at the same time, same pictures, on eBay and Jackpot. I tried to remove all variables, except the locations.

Since I didn't track views, I'd say someone should do the investigation and cover it properly on all three of the services.

Once again I'm not out to rip Jackpot, it might be that I sell Wisconsin and Elko and common stuff, but not one bid there and everything sold on eBay. Other items might do better on Jackpot.

If someone is going to do this experiment, it should be done blind, without notice to anyone. Standard experimental practice, if someone knows there is a test going on, they could alter the outcome.

Also using one chip on all three might skew the results. Say there are more Strike collectors who frequent Jackpot (which I think there are) and less AC collectors, the chips should be from a few different areas, to be fair. (I suppose Las Vegas chips are pretty universal for collectors and could work)

One $1, one $5, one $5 LE, one older chip, one roulette. A nice sample to put up on all three services.
