Received a seemingly common Presorted Standard Stamp (Scott 4157) on a cover addressed to me by a local bank. Upon closer look, the stamp has the Plate Number V333, and while listed in my Scott Specialized Catalog, it offers no value but just indicates ( - ).
Does this mean that it is too new of a variety to have established a value, yet it is going to be different than the values listed for Plate Number V111 and V222? Are the V333 plate number stamp on cover a scarcer variety?
Also note the relatively poor registration of the colors and the "snowflake-like" blue background.

I suppose it's worth keeping on cover to show it's postal use.
