Strange coin, the 1992 10P : two different planchet sizes and weights for circulation coins:
1. copper nickel 11.3 grams, 28.5 mm diameter
2. NCLT silver proof 13.2 grams, 28.5 mm diameter
3. copper nickel 6.5 grams, 24.5mm diameter (pictured).
The similar weight and diameter would provide a reasonable explanation as to why this coin was found in a roll of Quarters.
4. NCLT silver proof 7.6 grams, 24.5 mm diameter
5. off metal strike, struck on a bronze planchet.
The Royal Mint is notorious for off metal strikes, because they execute coinage orders for the circulating coinage systems of a lot of British Commonwealth countries.
The British are not up to anything, it's just that mechanical coin rolling machines are fairly brainless.
I have an example of 1, 2, 3, and 5, all of 1992 date.
