Silver Searcher Explosion?

I was chatting with the teller at a branch last night while my coins were counting. I asked if she had any halves and she told me no, and in fact, she was amazed at how many people have been asking lately. She said about a month ago, people started asking all the time. She said that at least one person comes in to ask about and/or order half dollars almost every day. They are ordering in multiple boxes a week for people. I know that this is true at another branch because I tend to get the box scraps (they dont take home the whole box). This new information combined with my recent conflict with the credit union over halves, I think I'm going to switch to dimes and nickels!
