I spoke with a couple of dealers in my hometown because I wanted to put some of these nickels away for my two young grandsons. They both told a different version of the same thing:
1. The first who has been in coins for well over 30 years said that he feels that the nickel won't hold up in circulation. When I asked him what he meant, he said that he felt that the nickel would wear down quickly and that the uncirculated nickels would attain value quickly.
2. The second dealer told me that he thought that the nickel was very sharp and he said he wouldn't be surprised if someone actually cut themselves on one of them. Then he laughed and said that they could sue the mint and the mint would discontinue the run.
Don't have a clue with the validity of these statements, just thought it wan an interesting add to this thread
