I am a big type collector myself and been doing a 7070 forever it seems likeand have done a little bit to my 7070, I added a modern commemorative page to the back which I filled up with all the modern comm halves. I am not a
Lincoln Cent fan at all and couldn't see myself adding to my 7070 like that. I wish they would do some more modern coinage and revise the 7070 but I just find myself doing different sets in addition to the 7070 like the Whitman 20th Century album and the Whitman 20th and 21st century type album. I am thinking of one day doing them all, 7070, littleton, whitman, intercept shield.
I just love type sets so much my newest project is going to being doing a crowns of the world set mixed with modern bullion. So a old canadian silver dollar and a maple leaf, a morgan and a silver eagle, a british crown and UK brittania coin.
