Is this stuff really worth that much?

I have been looking at the price checks for some of these items people list. 100k, 200k, 300k etc. What makes these items worth so much more? Why are Gold items worth more than Greens? The Mods on both are maxed out , right? How do you determine what something is worth? Sorry to sound like a noob but its something I have always wondered.

expensive factor: low rq, rare skin/name, high demand and low supply

green = cheap becasue they are in high supply

Thank you

PC's are subjective. Things are worth only what someone is willing to pay for them.

agreed...
