I picked up a change purse filled with wheaties at a yard sale a couple days back. Upon searching them this morning, it turned out about 95% were very ordinary 1940's & 50's types (although about a dozen of those were AU/UNC). I guess if under those circumstances you're going to have an outlier, short of really lucking into a 1909-S VDB or a 1914-D, a 1913-S isn't too bad an issue to come across.
I'm not sure why that might seem odd. That's what they were stored in, and I wasn't about to pour them out and stuff them in my pockets! And actually it was convenient for me to put the several other coins I bought there in it for transporting everything home.
