Looks to me like the one on the left is an example of

and the one on the right is an example of

If you measure the full height of the stamp (to where the top and bottom would be if it were pressed in fully) the one on the left may be taller (1.5") and the one on the right shorter (1 3/16"). Or they could be the same height. They might be the same die but a pressing with two different force settings. I'm still gathering observations on how variable different pressings of the same die are. Obviously if they are quite different in height they are different dies. But if they are the same height and only vary slightly in how different portions of different letters are pressed in? Not so clear cut.

Are the two hats about the same weight? Or is one heavier like New Beats tend to be?

The top hat is 830 and the bottom hat is 1260.

The stamps appear to be the same height but the one didn't get stamped very good/hard.

Thanks for that info. So yes, New Beat weight ratio. My favorite pair are 732g over 1120g, but they aren't a factory New Beat pairing. I purchased them separately and they are unusually light. Having tried a few different New Beat pairs, and done lots of swapping around of different tops and bottoms, I decided what weights I would like and went looking.

The weights seem to be a good combo. They sound awesome!
