I'm not sure if the data will display properly but here goes. I've examined the data by mintage. I made no adjustment based for silver nickels. To make the math easier, if a coin had a mintage of 160,738,240 I used 160.7 as the mintage. The weighted average was calculated by multiplying the number of coins of each mintage between 1938 - 1959 (
Jefferson nickels only), summed that calculation then divided by the total number of coins for the period 1938 - 1959. I generally used 100.0 to indicate whether it was a good box or not. The average for years 1 and 2 are 110.59 and 109.35
Here are my results. I would be interested in any similar results from the rest of you. As it shows, silver is getting more scarce. The distribution across the three mintage bands are remarkably similar across the period.
