The Three Cent CPVs using my SQNS (Small Queen Numbering System) (Blue numbers are 'active links') All varieties are constant, with at least 2 copies seen/reported.

An attempt to show up to ten reported dates for each CPV is being considered. If successful, it might look something like this.

In the future, reports of additional dates will be welcome, but at this point my efforts are better directed towards finishing the CPV information.
