ijn1944 Bedrock of the Community United States 19113 Posts	Posted 08/30/2021 07:31 am On a mint-fresh coin like yours, 'toning' is the result of the coin's exposure to environmental agents and the initial 'color' of the planchet. While fresh planchets are nearly identical tone-wise, there can be subtle variations. I've see this often with state and sometimes ATB quarters--with fresh coins from the Philly mint occasionally having a slightly 'warmer' look to them than those from Denver. What does the obverse look like? Report this Post to the Staff
