When selecting a coin that represents a good value for the grade,
consider the price differential between grades.
For the 1946 Iowa Statehood Centennial commemorative half dollar the
price jump between a lightly circulated example and one in a solid
mid-range Mint State grade of MS-64 is only around $20. At recent
auctions, lightly circulated About Uncirculated 58 representatives
have brought $85 while MS-64s and even the occasional MS-65 can be
found for a little more than $100.
For $200, one can find the occasional MS-67 example certified by
either Numismatic Guaranty Corp. or Professional Coin Grading Service.
For example in a March 9, 2014 auction a generally brilliant example
graded NGC MS-67 brought $199.75. Exceptional MS-67 examples with
great eye appeal can bring as much as $500.
The Iowa commemorative half dollar is an issue which “comes nice”.
This means that examples are generally well-struck, have good surface
preservation and full luster, and many were saved around the time of
issue in nearly pristine condition. As such, the population of MS-67
examples is high, meaning ample supply for commemorative coin
collectors which keeps prices at reasonable levels.
