thank you parcelpostguy, for some good leads on where to search.
So far, I found it to be either an RD12 or an RD30. The Eric Jackson's website was instrumental, as well as Hipstamp. Also my Scott Specialized Catalogue was of great help as well. The used value for this stamp is .25-.30 cents, not exactly a money maker.
Now I wonder what to do with 200-250 of these stamps
