I don't get excited about common, un-toned, clad Kennedy's usually. However, these guys are off the charts with eye appeal and luster... Obligatory new toner.
So the "dot head" or "birthmark" die ,as I know it, is the number one die for that date. It is quite desirable and brings a premium when they come for sale. That die pair have the highest rate of deep cameo of any die. If you find one, you are virtually guaranteed of a deep or ultra cameo designation. You could purchase a raw one for a couple hundred bucks and still come out on top.
Some of those are going to grade quite high. I think you hit the jackpot, especially on some of those market acceptable toned ones.
