Question
I have a 1971 Kennedy half dollar that has bubbled on both side but different areas and I was wondering if it would have any significant value. I will enclose both sides if I can. On the front side the bubble is from half way between the 9 and 7 up to the Y and the other side is bubbled quite a bit in the areas between the tip of the wing span. Thanks

Hello Beverly,
From the mint the coin would have had to be perfectly flat after being struck. The sheer pressure of the upper and lower dies closing on the coin blank would straighten any imperfections in the coin. Your coin has been altered or heated causing this condition. Altered coins have no added value.
The photo the web site here is showing me shows that heating of the coin may have happened.
If the coin seems to be acceptable weight, it should be 11.50 grams. It may be lighter if some of the metal is missing.
It is likely the metal sandwich of nickel covered copper the mint uses was near the end of the roll and the clad layers were not as thick as they should be, or a contaminant was present between the layers. But usually when this happens the design is not fully imparted since the metal was not sufficient to strike up properly.
I can direct you to a trustworthy coin person in your area. With out seeing the coin it is only a guess as to how it was made.
Write me back in a private question and let me know your general location using the nearest large cities and some zip codes in your area, I can direct you to an AMERICAN NUMISMATIC ASSOCIATION MEMBER/DEALER near there. They are ethical and trustworthy.
Thank You and Good Luck
