That's a lot of useful information in a very compact format.
The most interesting item to me is the last, in which it's revealed that the decline in demand (and thus minting) of five-cent pieces was due to the issue of so many dimes during the Specie Redemption years of 1875-78. Nickels were not coined for circulation at all during 1877-78, and only tokens numbers were produced 1879-81. It wasn't until 1882 that demand picked up for them and large coining resumed.
It's also notable that mention was made of a very recent increase in the demand for cents. Clearly, there was very little in 1877, when fewer than a million were coined for circulation, but mintages increased starting 1878, the time of this article.
Thanks, Roger.
