I can attest to Simon's post about the lack of any WAM cents here on the west coast. I go through 4 boxes a week and have found only one 2000 in the last year and a half.
I can't find any WAM wish I could be nice to have just like state quarters there are 3 I can't find to complete my book can't find oklahoma-p us virgin islands-p and northern Mariana islands-D and I put quite old bit of money in quarter machines trying to get them
All the 2000s I find are dirty and ugly. If I see a super clean 2000, there is a 99.9995% chance it will not be a WAM for me
Found a very nice 1998 WAM today, my eighth of the year. Also have four 2000 WAM's to my credit. Again, an hour and a half northwest of Philly.
