One cheap ring

Both of these are stamped .925....sterling
The one on the right is a 'spinner' ring

Aussie 1938 Penny
Yet to identify the other coin(writing looks Thai)...........Looks to be a 5 Baht 1977/1979
Interesting that they came out as a double out of the same hole....If only these coins could talk :)
