I´d like to sell a "Horns and Roses Band Jacket" and it would be nice to know how much I would get for it. Thank you in advance.

I paid 1.5k CSC for mine not too long after it came out, I think I've heard more recent estimates closer to 1k for the other items, so I'd say anywhere in that range, personally.

so I could easily sell it for about 70 Million ??

You could try. 1.5k CSC was probably closer to 50-60m around that time

I looked at the prices for CSC 1000 CSC about 50 Million 500 CSC 25 Million soo I guess 70 Million would be fair
