BlankSlagle.jpgBlankSlagleb.jpg
just my opinion-the ad was not printed on the reverse-left for scrap, hand cut. I have a handful of them and all are not factory cut. The Slagle is probably 30 bucks with a Piedmont reverse and 300 with the blank reverse-but just my opinion. I am sure other collectors see them differently than I do. If you watch you will be able to find a blank reverse 206 at auction.
hope this helps
