Listed here is a genuine early 20th century "Perfect Tee" sand tee mold. Sand tee molds used during the wood shaft era are, today, inherently rare.  Consequently, replica's are being reproduced—and they are popular (they often sell for upwards of $75 or more) because the genuine articles are so hard to come by. The auctioneer has verified that this is indeed an original. It has the knurled edge around the top of the plunger as opposed to the serrated edge on the top edge of the replicas, etc. This sand tee mold has its original working spring and clear lettering--marked as made by the Olson Manufacturing Company in Albert Lea, Minn. beginning in 1910.
