I really like the 112; so much so in fact, that since the first time I held one, I lost my desire for most anything else. Unfortunately though, even nice older ones like yours don't seem to command very high prices. Just before the holidays, I paid $70 for a new old stock 2-dot 112 complete with its original box, sheath and paperwork. The knife arrived with a note from the seller saying that he had three more just like it. I bought those as well, gave two away as Christmas gifts and kept the extra one as a spare. My point is that these 2-dot (1974-1978) 112's in new condition only commanded $70 each. But to me, they are worth far more both as stout users as well as to collect. If you like your 112 at all, I'd say keep it, use it, and enjoy the now rare solid Macassar Ebony scales, nice blade steel, and solid feel. The moderns are nice, but for the relatively small amount of money the 112 will get, you might regret selling it one day.
