Misunderstanding Of Missing Clad Layers And Whether Weight Is A Tell Tale Sign!

I agree with @cmey. Knowing the weight will not provide a definitive diagnosis of a missing clad layer, but I find it to be a really valuable first question to ask. Here is a quote from Mike Diamond's website:

I would like to know who is this "expert rare clad coin Dealer".

A lighter than normal weight is a good diagnostic tool that can be used to determine if a clad layer is missing. But the appearance is also necessary to be looked at as well.

A missing clad layer is a coin that has one of its outer nickel layers missing from the copper core. As a result, the typical missing clad layer coin will be copper on one side and nickel on the other. It also will weigh roughly 15% less than a normal coin so thats why its a good thing to check but not always going to be different in certain cases so as mentioned might use coloring and other diagnostics. Your more than welcome to post up any link to further info the dealer had gathered regarding the weight. There are full, partial, or dual missing clad layers, with each type representing how much of the clad layer(s) is missing and happens on dimes, quarters, halfs, and dollars since 1964 but not nickels. One other type of missing clad layer is called a "dual missing clad layer," which is a coin missing both the obverse and reverse clad layers, with only the copper core remaining. Such a coin will be copper on both sides and will weigh approximately 30% less than a normal coin of its type. The dual missing clad layers are incredibly rare, with less than 10 known for Roosevelt dimes, five to 10 for Washington quarters, and only one for Kennedy half dollars, and none are known for the dollar coin series so its not discussed often.

There are also for example Nickels struck accidentally on one cent planchets that can look copper so not always environmental toning in those cases when its not a missing clad like in a nickels case. In such examples, the planchet will be both the weight and metal content of a "normal" example for the respective planchet it is struck on. For example, if it is a nickel on a cent planchet, the coin will be the correct weight for a cent at 3.1 grams and contain the copper alloy for a cent rather than the expected 5g for a nickel planchet.

Yes, those can be included in the list. NGC has certified a James Monroe $1 Coin missing clad layer. Presidential dollars are composed of the same three-part clad layers as the Sacagawea dollars. Planchets missing an outer layer show one side in rich copper color, as the pure copper center of the coin is exposed. This bright red is a sharp contrast to the "golden" appearance on the other side of the coin, adding to the drama of this error. Because coins missing a clad layer are thinner than normal planchets, they show weakness in the design especially along the edge of the coin. The image and some other Presidential dollar errors are discussed further in the link.
