Hi, Going through some 1974 quarters and came upon one that weighs 5.81g! Cool considering that 1974 is my birth year.  Marlies  Edited by EML Coin Collector 09/19/2023 09:59 am

5.443 to 5.897 is within tolerance for a clad quarter.

That's still within tolerance for a normal clad quarter. Is copper visible on the edge?

Regular quarters are around 5.5-5.6g on average and silver quarters are known to weigh 5.75g. Something's not adding up...

Yes, but there are like part copper and part silver ones out there too aren't there? 60/40 or something like that? Apparently some 1977 quarters have that makeup too due to transition period.

You've got an hour to post a pic of the edge or I'm locking this.

There are no part-silver quarters. You're thinking of half dollars 1965-1970.

That's a normal clad quarter, a tad overweight assuming your scale is correct, but within tolerance.

==Coinfrog== https://coins.thefuntimesguide.com/...arter-value/"1977-D Silver Quarter Error When the 1776-1976 Bicentennial quarters were being struck, some were produced at the San Francisco Mint in a special 40% silver format for collectors. However, some of these silver planchets were somehow processed by the Denver Mint — which inadvertently struck some 1977-dated quarters on 40% silver blanks intended only for the 1976 quarters!" Supposedly the same thing happened to 1974 quarters since it was during a transition period.

Yes-considering all the others were averaging 5.5-this one really stood out!

The 40% silver does not show copper on the edge.

So that means that the quarter is predominately copper which would make it similar to a copper penny from 1982 back? Seems to me like a quarter to keep for that reason then!

All clad quarters are predominantly copper. The composition average is 8.33% nickel, 91.67% copper. The core is solid copper, and even the cupronickel faces are 25% nickel, 75% copper.
