Do characters actually sell on the marketplace?

[sirswine2]

Hello everyone, I am new here. I took a look at the character marketplace and I see the prices of characters, minimum 30 coins and sometimes up to 1000.
My question is do people actually buy these characters? And what do they look for in characters to buy?
