From the USPaperMoney.Info website;
Another group of experimentals was printed in Series 1935. Again the test involved three batches of notes: one on paper with a special finish, numbered A00000001B through A06180000B; one on special paper, numbered B00000001B through B03300000B; and a control group on regular paper numbered C00000001B through C03300000B. These serial number ranges are above any others used on Series 1935, but they do fall within the ranges used for Series 1935A. I've not been able to determine whether the same serial numbers were used again in Series 1935A when the regular print runs reached these blocks.
You can create a "want list" on many auction sites and research recent prices on the same sites. Sounds like you want us to find them for you.....where's the fun in that ?
