Kalashnikov Bayonets of the World

What is the best advice you guys can give me as far as collecting . I have quite a few and by the looks of it i have a ways to go . But if you had to do it over again what would you say to yourself say a year or two into this . I enjoy looking at some of your guys collections they are amazing.

Condition, condition, condition.
"Been there, done that" condition doesn't add value. Neither does stories unless they have concrete provenance.
Buy the best condition ones you can find, and matching numbers. Try and upgrade your examples until you have the best ones possible.
Don't be afraid to sell lesser ones to upgrade others. You are collecting, not accumulating. It's not about quantity, it's quality.
Just my own personal opinions.

Thank you for the response you make a good point About the collecting part.
