For sale today is a scarce 1935 (plain) $1 Silver Certificate Fr 1607m Mule. The 1935 series is fascinating in that it was a single issue variety with a double date, and was immediately changed with the 1935-A series and all following notes had a single date. This particular bill is a very late serial for a 1935 plain, being in the Q-A block, and is the rare Mule variety printed on a 1935-A back with macro plate number. This is a very scarce and under-appreciated Mule variety and should be a good sleeper for value. 

The note grades a Choice Fine in my opinion with nice color and no pinholes. Please check scans and judge grade for yourself. Thanks for looking and have a great day!
