I'm vacationing in Maui so I thought I'd check out some pennies from around here. I went to 2 different Hawaiian banks and bought 50 CWR from each. The Post Office was right there so I got a medium flat rate box and put a whole roll of tape on it. It cost about $16.50 postage. There were a lot of brown enders so hopefully not too many shield cents. The last four boxes I got in California have been skunk so I'm hopeful to find somethin in those ones.
