NY Subway tokens

NY token 2
Originally uploaded by a1scrapmetal

Whist looking through some drawers in my workshop I found another token, which I bought back from a visit to New York ten years ago.
(the one with the Y I got off a flea market in NY last year).
Both have
"GOOD FOR ONE FARE"
on one side, and
"NEW YORK TRANSIT AUTHORITY"
on the other side.
