Cut Victorian coin.

Probably PMD. If not, any info about this coin? It diameter is 32 mm. The cut mark looks like it was done a long time ago. Thanks. 🤔🙂

N#19488 

32mm / 1839-1864 

Somebody did a test if it's silver (the hole in the middle) but wasn't too sure so it was cut in half?

Or maybe the half crown cut coin was meant to circulate as a two-shilling piece due to a shortage of those. So a half crown ‘loses’ six pence by cutting off a piece of the coin. The hole is anybody’s guess. I know stamps were cut in half diagonally so maybe that what happened here. 🤔

Heres an interesting thread about cut coins. However mine is not that old.
