Those models do have more value to some folk since they had the "beavertail" type grip safety I think Colt sourced from Caspian and some other bits that changed in later years. The most obvious visually is the "duckbill" grip safety Colt started to use. Here for example is a 2006 XSE LW Commander in 45ACP I bought new that year.
For value I would search gunbroker and other online sights and see what examples sale for, not what some people want for them.
Are you an investor or shooter?If you're a shooter looking to sell or buy, a used pistol is worth slightly less than a new pistol - assuming that it is identical condition and even less as finishes wear, night sights age, and the springs weaken. If you are an investor looking to sell or buy, gambling that it will be worth more because it has different contractor parts in it or it has a stock number that isn't used any longer, then best of luck. Every field of collecting has limited production stuff that should bring a premium and doesn't, while something else that was ignored for years or decades - now commands a premium. Speculative buying of potential collectors guns is a very risky move, because future generations decide what is wanted, not the speculators.I'd say it is worth maybe $50 more than an average Commander in identical condition, if one has to have front slide serrations and the other parts.
