I won this on EBAY and I'm just wondering if this is as rare as they say...Thanks for any help....

This is from the auction:

"This 1953 HARLEY DAVIDSON Advertising Poker Chip is extremely rare! Made by an advertising specialty company in Ohio but never circulated it was placed in a file cabinet in their warehouse where it sat for many years. The warehouse caught fire and it was found months later by the salvage company during clean up. We can offer documentation of this ( News paper head line and report along with a copy of the fire departments actual fire report ). There were very few made ( probably as samples )."
