Only sort of partial set I have is just a year only Large Cent collection. All of my other collections are whatever the Album manufacturers place in their Albums. My way of thinking about collections of coins is almost every one you can think of has so many varieties and/or errors that you never could find a set that is complete. And what makes it worse is it appears that almost every day someone is finding a new variety of a coin. Like large and small mint marks, over dates, Reverse of a previous year, etc.
