Big five: 1909-S VDB, 1914-D, 1922 no D, 1931-S, 1909-S
am I right?
True, true, true. Yet the 31S is no big thing either, although really low mintage, many are always floating around for a reasonable price.
The 09S is probably more difficult and higher priced too.
If you have a source for some large quantities, there are virtually many error coins in that series and if you know what to look for, you can usually find some. There is a guy on a web site called
https://www.coppercoins.com that has two books out on that Cent and lists many, many errors for almost every year.
Never know you may find a 1955 Double Die in change.
