Hugh C. Reilly is listed in the 1912 Bradstreet as a saloon in Kansas City. 2½¢ tokens were used primarily to make change for 2/5¢ or 2/25¢ purchases. Some places with pool tables were known to charge 2½¢ for cue rental.
Missouri is one of the states that has no published reference so rarity and value are not going to be easy to figure out.
