Not to hijack, but let me ask this. When you say "unused in box", what about unused not in box.
I think any unused Schrade is probably "collectible." With regards to Old Timer values, the rare models and variations sell at significant premiums with or without the original packaging and paperwork. Even the most common models are still highly sought after if they have an older packaging style or older tang stamp. The problem with those most common models, they were mass produced by the thousands and thousands so most serious collectors already have them.
To be specific, if you have a 34OT (the most common and most famous Old Timer model of all) and it's new except missing the box, you'll have no trouble re-selling it, but it probably won't go for a premium price; you could get twice as much if it's packed in an older style box and has the original paperwork.
The smaller models (12OT, 108OT, etc.), for whatever reason, don't sell as high as equally-common larger models.
Despite being less common and built with premium materials, many of the limited edition or special Old Timers sell for
less than the standard brown delrin models. Something about that 'sawcut' plastic I guess.
None of that is 'gospel' and I haven't done any scientific studies or statistical consumer analysis; those are merely my observations from years of auction watching.
