If it's a very low number,, such as a 2 digit or a 3 digit,, it can have additional value. If the condition is LNIB,, you definitely need the box & papers & all. I have a 2 digit Stainless ROA that I'd NOT sell for $1000. (Others might take that for one,,, but not me.) Mine only has 2 digits,,, & NO prefix in the serial number.
