The coin is rather damaged, at least I suspect it's
PMD.
But I noticed the date is a bit strange, especially the 5 & 4. Maybe it is an overdate?
I saw some other examples, and I read somewhere that there are varietys of the 4 ?

A Plain 4 & A Crosslet 4 (which is in my case)

My Coin with crosslet 4:
