$$$19th/20th Century Eagles on U.S. Coinage

Set Description
A great part of numismatics is the detailed study of particular coin groupings. Sometimes one has to think a little "outside the box" and find new ways of studying our coinage. Presented here is a modest example of such a grouping.
I think the original idea here is expanding the family of eagle examples with regard to the terms "heraldic" and "flying", and the use of the term "perched" which happily finds three nice examples. I hope the new term "landing" is fitting as well as it seems humorous! The dates given represent those years a particular design appears, irrespective of denomination. Because a coin's design may have changes, I've reflected those dates in this manner.
