Populations of 19th century coins
I rarely buy the same coin issue twice. just a trend of mine, once I have owned a coin I rarely buy the same issue again. However, I recently added an 1859 Seated Half to my collection. I owned an 1859 half previously, but had to sell it. Now I am doing a bit of a rebuild and found myself doing just that.
This is a totally empirical observation and is a sample of only one. But, I always keep track of the PCGS/NGC combined populations when I buy a coin. The combined pop in 2006 when I purchased the first half was 448. The combined population today is 612. My high school math says that amounts to a 27 percent increase in slabbed coins over a 17 period. Or, about 10 coins every year. I consider the 1859 Philly to be one of those coins that is not all that rare, yet finding a nice one can take awhile. To me though, I do think it offers some example of what kind of population of rare coins may still exist raw when it comes to in between dates. By which I mean coins that are not considered RARE so anything, any grade gets in a slab, nor so common only the highest grade pieces get slabbed. As I say though, small sample to work with since I so rarely duplicate. James
