As part of a promotion for the upcoming Fantastic Four: Rise of the Silver Surfer, 20th Century Fox joined up with the Franklin Mint to release a Silver Surfer quarter.
Oh yes, you read that right. The quarter, which has an image of the Silver Surfer on one side, is valid U.S. currency. In fact, reports Variety.com, 40,000 of the quarters have already been released upon the American public--courtesy special silver armored trucks.
While collectible coins aren't totally unheard of in the comic book geek universe, it's not so common for them to be actual valid currency.
Thus, for those who find themselves in possession of one of these rare beasts, be advised: you might not want to just toss them into the vending machine for another Fanta. At present, the Silver Surfer quarters are going for a between roughly $20 and $40 each on eBay.
Or you can go to the movie's website (fantasticfourmovie.com) and take part in the Search 4 Silver campaign--which has prizes such as special screenings and a trip for four to the movie's world premiere in London.
