coop Bedrock of the Community United States 62064 Posts	Posted 11/06/2017 12:31 pm Coins worth more than $25. A bad cleaning can reduce the value as much as 90% if not done wrong. Report this Post to the Staff

ClemCladhopper New Member United States 18 Posts	Posted 11/10/2017 09:25 am Okay, I weighed the half and it comes in a little light at 11.11g (11.43g was average) Could it be struck on a quarter planchete? Report this Post to the Staff
Coppergold Pillar of the Community United States 939 Posts	Posted 11/10/2017 1:01 pm No. This is what it would look like if it were struck on a quarter planchet.. Your coin is simply plated. The weight isn't that much to alarm me honestly. How many times did you weigh it? And did you press tare every time you re weighed it? Was the coin bigger than the platform you weigh it on? If the coin isn't dead center and isn't fully on the platform than it will weigh a lot less because the weight is falling off the edge of the scale. Did you weigh it on a flat hard surface? Honestly I would let this coin go... Report this Post to the Staff
Crazyb0 Rest in Peace 10197 Posts	Posted 11/10/2017 1:15 pm OP mentioned a bluish tint, this indicates a different surface layer. Possibly a nickel/tin mix which may have a very slight magnetic attraction, or even a silver plated alloy of silver/tin or even a zinc mix(tin/zinc being key to blue). Plating causes very silight weight differences, in the hundredths of a gram, usually well within planchet Weight Tolerances. Most likely is a science"project", check YouTube for vids of DIY.

coop Bedrock of the Community United States 62064 Posts	Posted 11/10/2017 6:12 pm If the coin was stored in a soft 2X2 flip, then it might be contaminated with PVC. So that is another suggestion for a purple color on a coin. Report this Post to the Staff
