I think it is worth at least 0.07 BTC at current prices.
that would be approx 7000 eur or usd. on TG someone is trying hard to sell a red 5 digit cs1 for 2200 eur and "is not getting rid of it". how do you come to the 0.07 btc/7000 eur/usd? your pricing would mean that the minor worth colours have a value of 4800 in total...
