Blank Planchet ID Help??? Size of quarter, but weight off.

Here I have a blank 3 blank planchets and 1 unknown. It is 19mm around, 1.9 (just short of 2mm) (same as Quarter) and weighs 6.55 Grams. Is this also a blank planchet.





The rim and size makes me think quarter; however 6.55 Grams. Thats way off. Maybe another country?

insight appreciated.

The others are obviously a dime and 2 pennies ;-)

 

Your size does not make sense. 19 mm around would be 6.05 mm in diameter or smaller than a silver three cent piece. 19 mm in diameter would be the same size as a Lincoln cent and it is obviously larger than the cent planchets you have.

 

Sorry I meant the dimensions are 24.3 mm, same as a quarter

 

Maybe a proof planchet since they weigh in at 6.5

 

I am new to coin talk and still trying to navigate thru pages. I would like to post an unusual error that is major but dont know how. Can you help me out?

 

It could be a blank proof quarter since they weigh 6.5

 

It's a slug.

It is not a blank or planchet
from any US Mint facility.

 

I had a coin blank just like that weighing 6.5 to. They told me it was nothing so I threw it away

 

I realize this is a 2 year old post:

In response to a 7 year old thread.

But I have to disagree that proof quarter planchets would weigh 6.5 grams.
The blank is showing copper, and would be almost 1 gram lighter at 5.67 g.
Please educate me if I am wrong.
