If you have a copy of
Crawford, several of your questions are addressed there.
You should not be surprised that you received one reply, from an enthusiastic and helpful board member, in just over a day. Numismatic research is not instantaneous; questions as to "whether" a coin is not included in a major
catalog are always going to be fairly complex. There have been several publications by specialists who have adjusted or added to
Crawford, but these are not instantly available. Learning about those updated ideas is one of the joys of numismatic collecting that goes beyond identifying a single coin.
As
Meepzorp points out, at least one of your coins presents an odd variation. To my eye, the photos show reasonably well preserved specimens, which raises my question: How did the sellers(s) describe these coins? (Which you should answer after reposting the coins separately, as
Meepzorp noted.)
