You have to know the weight of the coin in question first, then these things before going further to determine anything really.
What does the coin weigh?
What should the coin weigh normally?
What is the tolerance range for the coin?
Do you suspect that a coin you have was struck on a different planchet? Just show us.
I see more "missing clad layer" which will make it light, than it being light from any other reason and this only affects dimes and quarters half dollars and ikes since the late 1960s.
So what does a single measurement of 2.95g tell you?? Nothing...
It could be a 2.98g coin with some wear.
It could also be 2.95g pristine but one of the 5%
In fact, this is the first time I've seen it.
In previous discussions of tolerances, there's been an assumption that the tolerance specifies upper and lower limits on weight, and that the Mint should reject coins outside that range. If you expected 5% of coins to be outside weight tolerance, that would have big implications for authentication at TPGs, or for that matter in vending machines. (If 5% of coins can be outside tolerance, how far out can they be? Can a few cents weigh 6g? 60g?)
It seems like I've weighed a lot more than a hundred unworn coins, and found a lot less than 5 that were outside tolerance. I'm not sure that I've found any outside tolerance, in fact, except for ones that subsequently turned out to be fake.
2.76 suppose to be 2.5
What? A clad quarter is supposed to weigh 5.67 grams.
It's 5.78 when it suppose to be 5.67- my mistake I was weight pennies before and got them mixed up
