    I was looking into if I wanted to add more of the modern coins to my Prime Number set. 1979 is a prime number, and as the year is famous for one of the worst mistakes in US coinage, the SBA dollar (derisively called the "Jimmy Carter Quarter"), I figured it would be fitting to use a mistake to represent that mistake. Purchased from Fred Weinberg.

    Really wish they had gone with the breathtaking original Liberty design

    I think adding modern coins into your set is a good idea. Some of the prime year modern errors are nice looking. Year 1999 also has lots of errors.

    Here are 2 of mine. They belong to the same error type, which is struck through detached clad layer.

    Neat coins, very similar in appearance.

    I think I have most of the modern dates I need figured out. I will probably only do an error for 1979 to highlight the error in introducing that coin as it was. It's a really attractive SBA, very clean cheek, graded 66. The modern years I have left are 1987, 93, 97, 99, 2003, 11, and 17, and I have most slots figured out. 87 Constitution $5, 93 ASE, 97 MS Plat, 99 Kennedy half (may switch with 93, depending on which Kennedy I can find that I really like first). 2003 is going to be a toned proof Sac $1. 2011 and 2017 will be a gold Buffalo and ATB quarter -- not sure which will be which. The earlier dates are harder to plan, and tend to be a fun surprise when I find one that fits. 1709 and earlier means I'm strictly into world coins. One will be a Lion Dollar, but finding a really attractive one will be a challenge. I have gold for every century 16th - 20th. 15th century dated gold will be tough, but it exists.

    This would be it if you stuck to only federal coinage. When you see 1787 and 1783, colonial coinage beckons. 1789 has no dated coinage, but it's the date shown on the Mott torn. 1723 has all the Wood's coinage (Rosa Americana, Hibernia coppers). French colonials are available, as are Spanish colonial silver and gold, for the rest of the 18th century.

    I love the set for my money that 1693 shilling is the best

    Thanks. I want the set to have a little bit of everything -- something for everyone.
