Hit On A 1963B Series Bill

I like entering older bills onto Where's George?, to see if they get good hits. This morning, I got a hit on a 1963B series bill that I entered in September of this year. I do not have many hits of the older bills I guess it is because there is so few of them. I only have two 1963B entered on Where's George? this hit gives me a 50 percent hit rate for 1963B series bills.
