If the number is 200 or below w/a V (for "variation") following the number, it's almost certainly a Collector Club knife; most likely a Sprint variation.
However, there are certain knives that have numbers less than or greater than 200 and these may or may not be a Collector Club knife but a "limited edition" knife that was instead made in collaboration w/another company.
For example, I've got a vintage Spyderco Peter Herbst designed Ti knife made in Germany by Solingen that is numbered over 900 (on the clip side; not the show side next to the Spyder logo) but that number is apparently meaningless because I was told that those knives could have been made w/pre-numbered blades in no specific order.
Don't know if it matters whether the number is located next to the Spyder logo or not but I think all Collector Club numbers are on the show side next to the logo.
I also contacted Spyderco in Dec 2018 to inquire about joining the Collector Club myself. I was sent a variety of information, including a list of 136 numbers that I could choose to select from which ranged from 018 to 197, which means that there were only 64 members of the Collector Club at the time of my inquiry, who may have chosen the number they had themselves or were given it arbitarily by Spyderco.
So, I do not think that the number on any Spyderco knife should affect its value in any way and I'd buy the knife only if I wanted/needed that particular model and I could get it for the price I wanted to pay based on its condition, regardless of whether it had a number on it or not.
Also, if I had a choice, I'd rather buy a knife w/o a number on it, because I think it looks better w/o a number on the blade and the absence of a number avoids any issues about whether its worth any more/less than another simply because it is numbered.
