Counterfeit quarter?

to get change for the el on Saturday, i bought a vanilla frappaccino from the convenience stand inside the el stop. i took the change, and went over to the cta machine to fill my card. i put a single in= $1.00. i put a quarter in= $1.25, and another quarter= $1.50, and the final quarter =$1.50. the machine spit it back out. so i repeated procedure. no dice. Four times i tried putting this quarter into the machine. Then i looked at it. At first glance i thought it was a franc, then maybe a Canadian quarter. Nope. This quarter had the phrase "United States of America Quarter Dollar" on it, but that my friends is where the similarities end. There was no George Washington bust, no states on the back, not even the familiar eagle of the pre-state quarter days. This was clearly a counterfeit quarter. The date on the "heads" side (i'm guessing here, because i have no idea which side is heads if George Washington isn't on it) is 1919, and features what appears to be Alexander the Great standing in front of a log cabin, holding a shield and an olive branch. The "tails" side has a picture of a either a hawk or a condor in flight, with stars around it and the phrase "e pluribus unum" in between it's wings.

A forty second search on the internet has led me to believe that this is, in fact, a rare 1919 "Standing liberty" quarter, worth anywhere from $50 - $1500. so, jackpot? That would buy like 28.57 - 857.14 el rides. i guess i'll call an appraiser today, which is one of the six phrases i thought i'd never say.
