So which M9 is the most valuable?

[saylor_n]

I'm an old retired military guy with a butt load of friends and over the years I have aquired several M9s. I never paid them much heed until one of my national guard buddies turned me on to this forum. I have briefly examined my bayonets and it would appear that have several varieties, all in varying degrees of condition. I had no idea that some of them could be worth so much. Is there some sort of table or chart saying what I could get for them?
