I believe all certified used copies of 125s have contemporary duplex cancels of the late 1870's. The bullseye, target cancel on this stamp is contemporary and consistent with an 1869-early 1870's cancel. That's not saying the cancel could not have been used on a special printing, BUT no expertizing service has or will certify any used 114 as a 125 no-grill stamp with this cancel. No used 114s will be certified as a no-grill stamp. Exception: the only certified no-grill 114(s), according to Bill Weiss (as I remember from the previous discussion) had a very large part original gum, therefore the expertizing service (don't know who) was apparently comfortable with certifying it/them. The only other no-grill 114s certified are for mint stamps with ample gum remaining on the stamp. There was a lengthy discussion on this topic regarding 114's-125s and the no-grill etc. here maybe 1-2 months ago. You can probably search it and read that discussion.
