Weight needed. I would think if both ni layers missing it wouldn't strike up this good. There is some mushy details, and you can see some nickel on the top of the head and the tips of the feathers. Hope it is missing both, but not holding my breath.

If it were missing cladding, the color would be red and not brown. Also the color is wearing off on the higher areas of the devices and the rim. Not a missing cladding.

Waiting to see what others think since it is underweight.
This one has a different appearance than others I have found metal detecting, but that may be from being rubbed since it was found.

(Normal is 5.6 grams)
Yours is about 11% underweight.

Myself, not knowing much about it, would think that 11% is a pretty good bit to be missing.. what do you think

The surface details are soft and absent in some areas. It's far too heavy to have been struck on a copper core. I have never seen a full diameter copper quarter that approached the weight of a normal quarter. While such an error is theoretically possible, this ain't it. Everything I see tells me it is a genuine quarter that has been monkeyed with or a struck counterfeit. There are plenty of copper 25c counterfeits from earlier years.

For ALLs: An quarter without clad must be around:

1 side missing = 4.96 gr
2 sides missing = 4.25 gr

Your numbers are wrong, Silviosi. A quarter clad layer weighs 1 gram. Therefore, a quarter missing one clad layer will weigh 4.67 grams. If missing both clad layers (i.e., struck on a copper core) it will weigh 3.67 grams. There are exceptions. If one clad strip ends prematurely in the rolling mill, the resulting blank will be close to normal weight. Every example I've seen of this rarer type features a taper. In fact, every clad tapered planchet error I've encountered is missing part or all of one clad layer.

Thanks for precision MIKE. I give just mathematical calculus base on 25% clad, I do not have in my hand the Mint really specs. I will ask and put to all coins lover the exact numbers for all coins.

How can we test it to know for sure

Go by the weights that Mike Diamond gave you.
If it is missing the clad on both sides, it would weigh 3.67g
Can't be any easier then that.

Missing vlad layer does not always imply missing weight if I'm not mistaken
