Pentref Llechwedd village

I have a 1991 one penny Pentref Llechwedd village token.  Can anyone tell me why this was issued and whether it has any rarity value?

here's a little info about them.

Woodfen does mention that the coin he has is a penny so it probably won't be that one, the half penny also exists from the same mining village. I will add the half penny to the catalogue a little later.
