I found an '09 sacagawea dollar in the register at wark last night. It kind of surprised me to see a Sac this new looking so I looked for a date which wasn't there. I flipped it over to see the new reverse and realized it was an '09 with edge lettering. I didn't think they were going to circulate.
They circulate because people use the direct ship program. I ordered several rolls and use them whenever possible. Maybe that was one of them!
