Plastic bar tokens are generally on the low side of the value. LCS has half an album of them from Michigan. they are either in the bargain bin 50% off marked price to $1.00 when they are in the album they are they can go for up to $2.50. This depends on whether it is still in biz or gone. The subject matter also has some thing to do with it first name bars are popular with people with the same names. Most of the plastic good for drink ones in my collection are from either fraternal group bars. or bars that are in the tourist/hunting areas, and are souvenirs. Just because they aren't attributed doesn't mean the are rare or worth more Car wash tokens tend again to be on the lower side as there aren't as many collectors. and tend to end up in the spare change jar when left over from the car wash trip.
About the only ones that have value are the coal script/company store ones. But it will depend on who and where they are being sold, as I have bought some out of the bargain box for .25˘
