"Good For One Unicycle Ride" token on ebay

Just wondering if anyone knew why or what this token is that someone on ebays trying to sell that has “Good for one unicycle ride” stamped in it. Here is the link.

Looks to me like it is for “entertainment purposes” only. If you look at the seller’s other items at the bottom of the eBay page, they are things that have been pressed onto flattened pennies. These are novelties that you get at the amusement park, zoo, etc.

I would guess, somebody thought the unicycle token idea was funny and was trying to make some money off of the idea.
