A friend of a friend gave me these picks this morning. He said they were in his Fathers belongings that he got a few years ago. All that is stamped on these is the word "NATIONAL" nothing else. They are brand new except for some light scratching from being stored together. Before I use them I thought I better check in case they are worth $400 like the ones in the classifieds 
.
Sorry for the sucky cell phone pictures.
