I have a Charlie Chaplin Vanishing Coin Trick. On the front, it says Happy Chap. On the back, Good for 1,000 Laffs. It came with a pin to fasten it to your clothing and instructions for performing the trick, although the elastic has long since disintegrated. It also came with an advertisement for two other Happy Chappy items, a Charlie Chaplin Squirt Ring for girls and a Squirt Badge for boys. I even have the envelope it was mailed in (in pieces) and the stamp it was mailed with. I'm curious to know if it is worth anything?
