Regarding Juliets specifically...
They had serials from when they first came out in in 1999 through the end of 2004. Each serial had an alpha prefix to designate the colorway (frame finish / lens combo) followed by a numeric number uniquely identifying each specific pair (usually six digits but not for every colorway), then a "B" to designate 3rd gen, an "A" to designate 2nd gen, or no alpha suffix to designate 1st gen.
4th gen had no serials or other markings of any kind, from 2005 - 2008. 5th gen ran through discontinuation in 2012, with SKU number and frame size markings where the serial used to be, but no unqiue identifier.
