Is anyone familiar with this token

in Q & A Forum
Tom Corcoran is listed in some early 1900's telephone directories as a grocer. I have not been able to find any additional information. The token is made of nickel and measures approximately 23-24mm. The letters are all incuse on the obverse and the reverse is blank.

It's probably a unique piece. Or maybe only a few were made.

Probably not worth much though because of how specialized it is.
@DCW any info ?

No idea, but looks 20th Century. Probably a scroll through city directories in San Francisco could tell the tale
