Obv. To Sa Kan Ken - Land Chief Officier Ticket;
Rev. Go Monme -'5 monme' (1 monme - 3.75g)
local issue, fantasy?
Message from Luke Roberts, an historian of Tokugawa Japan who specializes in Tosa history, and teaches at the University of California at Santa Barbara (20-Apr-00):

I looked at your 5 monme Tosa Kanken rubbing. Tosa was a lords
domain on the island of Shikoku in Japan and it issued many of its own
coins between 1866-71. However none of the pictures of such coins which
I have seen look exactly like what you display. The shape of the coin
is like the Tosa Tsuuhou which is a 100 mon coin modeled after the
Tenpou Tsuuhou. Tosa also minted a large rectangular coin called a
Tosa
Kanken which had on its obverse side 100 mon as its value. Its monme
coins (units of 1 and 10) are all round. Tosa is present day Kochi
prefecture.
