I am trying to figure out what the stamps are on these coins. I am fairly certain the identification is accurate.
The 20 Para has one stamp that looks like “PM”
The 40 Para has 2 stamps, one on each side. One has characters I can't identify, possibly a “K”. The other side is also unidentifiable, one is an “X”?
40 Para N#10137
20 Para N#20387
Any information is appreciated.
