This is one is a series; I also have similar 10c, 1.00, 5.00 and 20.00 chips. My guess would be that this series came from the 1940s or 50s. The "Ox" has indeed been there a VERY long time...I have about 20 different chips from the place, in many different styles and versions, including several old crest & seals. The chips currently in use are hat & canes.
