JDcompy New Member United States 45 Posts	Posted 03/10/2012 01:03 am Hello! I've looked online a bit and am able to find the separate composition %s, but I am wondering if anyone knows the %s as a whole. (Hope that's clear) Thank you in advance! Report this Post to the Staff

Well, the silver clad Ikes have an outer layer made of 80% silver and 20% copper with an inner core of 21% silver and 79% copper. This configuration sometimes causes a "pink" ring on silver issues when the mix wasn't exactly perfect. The clad releases are made of 75% copper 25% nickel with a 100% copper core. This is what accounts to the copper "sandwich" look. Report this Post to the Staff
n9jig Pillar of the Community United States 997 Posts	Posted 03/10/2012 09:02 am According to Wikipedia the Copper-Nickel clad coins work out to 8.33% nickel and 91.67% copper. (http://en.wikipedia.org/wiki/Coins_...tes_dollar). The Ike dollar was of the same composition as the 71-current Kennedy halves, 65-current dimes and quarters and the entire Sacagawea dollars.

n9jig Pillar of the Community United States 997 Posts	Posted 03/10/2012 10:02 pm Yes, CaptainFwiffo is right, I meant the SBA's, not the Sacagawea. Sacs and Presidential dollars are made of a copper, zinc, manganese and zinc mixture. The Susan B. Anthony's were identical in composition to the quarter, half and dime as well as the Ike.

JDcompy New Member United States 45 Posts	Posted 03/11/2012 12:45 pm gotcha! While we are that topic, how come the pres. dollar coins tarnish different colors? some are VERY yellow, while others get dull. If they are made of the same metals.. why so different? Report this Post to the Staff
clairhardesty Pillar of the Community United States 1027 Posts	Posted 03/13/2012 3:48 pm The color differences arise because the metals used are very reactive and therefore very sensitive to the exact environments that they have passed through on their way to you. They will also vary just because of differences they encountered during manufacturing so even different coins in an original roll can end up looking different. Unfortunately, the "golden" dollars rarely "tone" in attractive ways. Report this Post to the Staff
