I know some of you live and breathe mint marks, so I thought I'd bring this to your attention. I was looking over my 2007 and 2008 silver proof sets and noticed that the "S" mint mark has been updated. It's different on all the coins in the proof sets (and probably circulation issues, too - I haven't checked). To me, the 2008 mint mark looks more like an "8" than an "S". I took these pics from the Half Dollars in the proof sets. See what you think (pardon my poor photography skills):

I know this is trivial, but some of you may find it interesting...
