Not to sound as ignorant as I very well may be but here goes. Are cuds and or die breaks considered a variety? And just how are varieties determined? Had heard someone mention that in one roll of 2018 quarters they had found 18 different varieties with a loupe, then went on to explain and show were it was that these "cuds" were to be found. Then I said well it has never really occurred to me just what it was the term variety really meant nor who it was that determined such. Somebody PLEASE clarify this for me. Thank you all for your tolerance .
