CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly.

    1966 Roosevelt dime with Annealing issue??

    Hi everyone, I'm a novice to coins, new to this forum, and this is my first post. I found two coins, a dime and a quarter. Below is the dime and I'll post the quarter (has problems) shortly.

    I found this1966 Roosevelt dime, (can't find mint mark), in pocket change about a week ago and began surfing for information. After reading an article by Mike Diamond on improper annealing I felt this dime might be in that category. Any information the forum could give will be very much appreciated.
    Thanks to all, Frank.

    It appears to be environmentally stained. The dull finish is consistent with this explanation.

      Mr. Diamond, thank you for taking the time to view my post. I felt because of the color and flaking the cause might be due to annealing issues. Thanks for clarifying this, Frank

        I know that my post is way after the fact but since it hasn't been specifically added.....Mike was right in his diagnosis...my addition is that the coin appears to be like every other copper-nickel clad coin that I have ever dug up while using my metal detector. I am fairly sure that your coin was buried. It also has an "east coast look" :-). many coins dug up in the Northeast look like this one.
