Way to Go Craig!!
I found a prototype in January and turned it into $2550.
Bill has Prototypes listed from $2000 to $5000 in his book. Although, I was told mine was only worth around $200, I got an offer for $1800 from Spain. So I decided to post it on eBay for a 7 day auction with a Reserve of $5000 just to test the waters. The bids were going up in increments of $500 so I knew I was going to see a nice return on my investment. I finally removed the reserve and got the final bid of $2550.
Although the market is supposed to be depressed right now, prototypes are one of a kind and still command a lot of interest with collectors. I strongly recommend that you give it a chance for people to see it and give yourself time to receive offers that are worthy of the token.
Good Luck with your prototype - this hobby is so much fun !!
