I have a 1980 P that weighs 5g and sounds odd when dropped on table. Looks normal. Was there any Quarter sized foreign coins minted that year? Rolled thin planchet? Dime stock? Thanks, John1  |

I have a spreadsheet of foreign coinage production figures. I will try to E-mail to you - if not successful, send me your E-mail address. It is an .xls format.

It is possible to be a dime stock. Maybe post a pic of the quarter in question in between a dime and a regular quarter

It's close to tolerance, a dime would weigh half that much.

On its way, Claude and John1 Thank you Pete! A nickel planchet weighs 5 grams, but looking at the edge it is clearly not a nickel planchet. It does look thinner than a normal quarter. It could be struck on a thin planchet. |

Not sure if Pete has the same spreadsheet as I. The one I have, Koinpro embedded it into a topic here about a year or more ago.
Shows three (other) countries this year being produced at Philly. None of which are exact 5.0grams, but all I believed show a composition of copper and nickel.
Maybe just rolled thin stock or possibly blanks punched using the wrong stock.
To figure the later I will not attempt to do. This kind of math and I are like a box of chocolate. You never know what your going to get. Thanks, Doug.

It may be the same one - cannot remember where I found it. It is .xls spreadsheet. I could not see a way to post it here. How do you embed something? I do not have a link that works.

There may have been an issue with the copper core of the metal on that coin. That would explain why the planchet could be light. I notice the strike is a little bit weak on the strike. So if the core was not thick enough, it could cause the weak strike and be under weight. I've not heard of this before, but that might be the cause? Note on the image of the three stacked on top each other, the bottom coin looks thinner than the other quarter.

Thanks for all the input. I have labeled it a rolled thin planchet. John1 |
