"I have four 1944 "No P" Henning Nickels, but I finally got one with one of the other dates after a couple years of searching. It is a pretty decent 1939, and iteven has the "Looped R." Weighs 5.3 grams.

"People just don't want to let these other dates go, and they are seldom up for sale. I am very lucky I found it. In a few days it will be off to ICG for slabbing asthey slab counterfeits. (I use them as educational pieces at shows.) Here are 2 of the 4 1944s I already had slabbed."
