What you have are the same strikes but stamped frosted early in the run and shinny stamped later in the run. In ordering generally the least a casino could order was 1750 without having to pay for the dies to be made. Some casinos had many thousands of the same strike made and just kept the machines with only those in it. There are some strike collectors who collect both frosted and shinny varieties. Generally they sell for about the same, unless you get someone who really wants it. And you know how that goes.
