Do You Save Jefferson Full Steps?

This is not exactly true. What makes a particular coin valuable is what makes it stand out head and shoulders above others of the same. Yes I suppose there is a basic value placed on a BU roll of 2010 P Jefferson's that may not move very much in the near future but that is for the average BU roll.
You could go through a solid box of 2010 P nickels and make a roll of the very best 40 Jefferson's out of that box and you would something very special and valuable in my opinion.
Finding several MS68. MS69, and maybe a MS70 nickel in the box certainly is a horse of a different color for value appreciation.

I voted yes for the nickels I have saved which amounts to maybe only 10 2010 P nickels.
