Title: Bi-metal R5 coins
Post by: Allen on August 01, 2013, 09:38 PM

Hi,
I found this R5 coin on the beach late this afternoon.
Galvanic corrosion is clearly evident between the two metals  (brass centre and copper/nickel ring).
I wonder how easy it will be to 'pop out' the centre brass portion.

I found one that has a copper rim. Could be a fake or could mean that the rim is also plated copper. Love em..

I found another fake non bimetal R5 in emmerentia dam but I seem to have spent it. Whoops!!
