Got several of these old Baldini's free-play tokens recently. Nice heavy brass, apparently same size and weight as a regular slot token and has a reeded edge. Appears to be unused with minimum bag-marks. I'm guessing these have been in storage for 30+ years and now that most everything is set to take paper, they are no longer needed.

These aren't listed in the Nevada Promo Token book.

I'll send you one for $3, postpaid. First requests get the nicest.
