In my experience the 101 has less collector interest than just about any other Savage firearm. However, my "experience" is VERY limited--I've handled and shot ONE and that is the sum total, plus reading reviews in gun magazines over the years.
You might do a search of posted discussions on
www.24hourcampfire's "Savage Collectors" forum and see what has been said about the 101 there over the years. I remember some discussions, but don't expect them to be positive about the 101: these guys are mostly 99 snobs, as are most Savage collectors. Not too much time for 101s, 23s, 340s, or even 219/220s!
One interesting thing about the 101 is that it used a cast Zamak frame and perhaps other large parts. Zamak was becoming popular for low-end firearms and quite a few different models by other manufacturers used it.
It is an alloy of Zinc, Aluminum, Magnesium, Antimony, and Copper (mostly zinc), The K in the trademark name comes from the German name for copper, "Kupfer."
Zamak can't be blued, so it must be painted instead. And paint can get very unattractive with hard use, as we see with 219/220 alloy trigger guards.
