I'd say it depends on the quality..
For example, the one you posted on your first post was very simple, i actually liked it and make one almost exactly like it in about 10 mins..
Because it didn't take very long, I'd charge like 500tc or 1,000tc depending on if you want to make tc or you do it because you like it. But if something is very detailed, and you put alot of hard work into it, you can sell it for like 7k tc or something. This is what I would do/ how I would price my stuff.
