Coins that will be up turned into rings soon

In the not to distant future I will be turning these pennies into rings.  I recently sold a Canadian 1915 Penny on Etsy and from what I can tell, copper coin rings are being search more often on Etsy and possibly becoming as popular as silver coin rings?

The top left coin is a 1 Penny from the former British Colony of Rhodesia and Nyasaland and is made of Bronze. 

The top right hand coin is a 1 Centavos from the Philippines when the Americans governed the Islands.  This 1944 coin is also made of Bronze.

The two bottom coins are Canadian Pennies from 1917 and 1920 respectively.  These two coins are made of 95% Copper and make incredible rings!

I take custom orders for rings that are made from Coins and if you have an idea or a specific coin that you would like made into a ring you may email me at oilydave@yahoo.ca or convo me at Etsy.com, (oilydave2day).
