    Inverted "M" Prefix Letter

    Inverted "M" Prefix Letter Fr. 1615 $1 1935F Silver Certificate. PCGS Very Fine 35PPQ.
    A very rare example of this unusual error variety where the "W" prefix in the right serial number is actually an inverted "M." We have known about the inverted "W" prefix letter error used as a "M" on 1957 $1 Silvers for many years, but this is the only example we have seen of an inverted "M" used as a "W" for the prefix letter of the right serial number on 1935F $1 Silvers. Coincidently or not, both the 1935F and 1957 $1 Silvers carry the same Treasury officials of Priest and Anderson. Both inverted prefix letter error varieties were made at approximately the same time based on the relative blocks within the ranges of serial numbers used to print these two series. The "W-I" block is slightly over halfway through the 1935F serial number range and the "M-A" block is about halfway through the Series 1957 serial numbers. Both of these errors were made the same way. The inverted "M" for the 1935F and the inverted "W" for the 1957 Series notes were put in their respective serial numbering wheels prefix letter slots upside down. This inverted "M" example has paper originality and is a nice example for the grade. It is certainly a "must" for the error collector looking to build a great collection.


    Estimate: $3,000 - $3,500.
