Wenth. All three firms told the NYCTA that the design of token desired could not be produced in the quantities needed for a widespread release in time for July 25, as the design required two additional steps (aligning and punching) in the manufacturing process. So the token manufacturers suggested a simpler solid design to get the NYCTA fare hike and token distribution rolling. Furthermore, the 16mm "Small Solid" and 16mm "Small Y Cut out" were compatible with each other in service. Due to the pressing need to get a token into service, the NYCTA also agreed to splitting the contract of token manufacture among all three firms (instead of just one) as well as taking deliver of the "Small Solid" first, and the "Small Y Cutout" second. The final batches of "Small Y Cutout" tokens would not be delivered until September 24, 1953. At this point the NYCTA removed the "Small Solid" from circulation by token clerks. Their short life span explains both their lack of recognition by most New York City subway history buffs, as well as the tokens rarity. As the "Small Y Cutout" tokens remained in circulation until 1970, they are prolific and stand out in the general memory of the transit user. In 1970 the fare was raised to 30 cents. This token is 23mm in diameter with a Y cut out, and is known as the "Large Y Cutout". The token did not always change with the fare: in 1972, when the fare increased from 30 to 35 cents, the MTA simply raised the prices of existing tokens (although a change in token size had been mulled). Another fare rise in 1980, which brought the fare from 50 to 60 cents, did result in the issuance of a 1mm smaller token (now 22mm) of solid design (no Y cutout) and is known as the "Large Solid" (as the 1953 solid was much smaller). For the 75th anniversary of the subway in 1979 (also called the Diamond Jubilee), a special token with a small off-center diamond cutout and engraved images of a 1904 subway car and kiosk were issued. Many were purchased as keepsakes and were not used for rides. A new design of tokens were issued in April 1986, which was 4 months after a raise in fare. These "Bulls-eye" tokens have a 8mm steel center that is magnetically attractive. There are three versions of
