1999d Deleware state quarter 5.0 planchet 0

[Mantha]

I have a 1999d Deleware state quarter that weighs 5.0 and is much smaller than a regular quarter. It has a thick copper like rim that is smooth

That looks like a dryer coin. Some times a coin will get caught between the inner and outer drums of a clothes dryer, and the rotation will wear and compress the edges like that.

It could also have been spooned. That is where someone repeatedly taps all around the edge of the coin, traditionally with a spoon, and flattens the edge. Spooning is the beginning step to making a coin ring.

Thank you any explanation for the 5.0 grams.

There is a mint tolerance of .19g on the planchets plus there would be material worn off the rims from the continual spinning in the drums of the dryer that would contribute to the weight loss.

Thank you so much. Just what if a dryer didn't do this. The outer rim is perfect no marks and the thickness of the coin is straight through. It is very thick. What do you think it would be just saying if it is not a dryer coin

There is no way it is not a dryer coin. (Or some similar machinery but still known as a Dryer Coin) Nothing else could cause this damage. The outer rim and smaller diameter is enough to tell it all. 

Just Bob mentioned spooning which looks similar but if it was spooned, there would be no weight loss.

Ok thanks

First what is the precision of your scale?  Is it actually showing 5.0 grams or 5 grams?  If it shows 5 grams you have a precision problem.  If it shows 5.0 then you have a coin that was a legitimate rolled thin planchet ehat has been ruined by getting caught in a dryer and has it's edge severly damaged.
