If it is mint NIB and complete, these are uncommon with no spotting, especially along the spine where curious owners touch them over the years, and no blade scratching, with full etch. Please note that I said uncommon, not rare. This scrim pattern was introduced in 1993 on the 502SC (Sharpfinger), a reissue of the buck scrim used on the 501SC (drop point hunter) in 1979. I could be wrong about the dates, but these are according to Levine's guide. The price they are asking may seem high, depending on actual condition, but it is not too far off the current retail value. I would be tempted to make an offer somewhat under their asking price, and (according to an old southern joke) if the lady is willing, be prepared to dicker.
