I bought four of these in July, 1964, at Baumgartner’s Cheese Store in Monroe, WI. The nickel shortage in 1964 caused a problem for small businesses in Monroe so the local bank “minted “their own.

I have quite a few wooden nickels and wooden flats too. Most all are coin related...clubs, dealers, shows, etc. Here's some from the Atlanta CC issued in 1954. Bruce
