Copper coin to identify

orgmr

This coin seems to be copper, or possibly brass? It is about 20mm and weighs 2.6g with a plain, but rough edge. One side has a large lamination obscuring some details. Any help figuring out what this is will be appreciated, thanks.

Thanks for the help. Does it have a date like KM145s or is mine also KM146 with the date error. I tried to figure it out but wasn't able to.
