It is a Japanese mon (cash) with inscription Kanei tsuho.  That was used with plain reverse from 1636-1760's.   It belongs to a subset "Shin-Kaneisen" = new Kanei sen, beginning 1668.  Approximate date 1736-40.   It may be a private imitation, from size and casting.   This is not my area, so not able to give an exact attribution, if that's what you needed.

I do not have bgriff's specialised knowledge, but the irregular border on the obverse and the inverse dent in the central hole are bizarre to me.

An unidentified coin is a piece of metal. An identified coin is a piece of history.

The obverse being shifted, but not the reverse, is from a mold slip, then the coin was finished to conform to the reverse rims.

In soft metal coins, like tin, a one-side centerhole deformation can be from string wear.  In this case it is probably from the shape of a rod used to punch out the center.  That's not normal for official ones.   It may have been hammered too hard, and down to its handle.
