i was metal detecting this morning on the beach (thought it might be good to try after the 4th) and i found this quarter:

it's obviously corroded...but, it weighs 5.67 grams. hmmm.

i did not clean it...i just pulled it out of the sand.

thoughts?

    They are clad and yes copper is the major element in them. And if you think it's worth more than 25c your wrong.
  • Planchet error copper wash or copper migration

  • Seen it a hundred times here. The salt water corrodes the clad layer and makes it appear as it came from the mint as copper. Just aint so, You can see the salt water etch under enough magnification. Found a dime last year, same thing. Agree with lindeDad, Its worth $.25

    yeah, i didn't think it was worth more than 25c...i was just wondering about it because the clad layer is so evenly removed and the details in tact. i thought it was worth some discussion, but apparently not.

    Been in the water so long the reverse design now looks like coral.
  • Have you ever seen weathered copper roofing or guttering? It tarnishes green like this.If a planchet spends to much time in the annealer it can cause the copper to migrate through the nickle to the surface .Copper on the surface would tarnish green.

    Typical salt water result on clad coins. Have seen them many times when metal detecting beaches..... Cheers, RickO

  • I do like the reverse as it looks like the trees around me that are finally starting to bloom even though it did snow north of us today.
