If you put it as "CC=400k and RR=500k" it would seem as if CC is correct and RR is incorrect. Besides, who would pay RR if it has only 500k value, they'll be losing currency.
If you do know market prices right now, CC is around 400k-500k and RR is around 700k-800k.
If the price you see has an obvious and too much gap from the current prices, it might mean the user made a mistake. As in my case, clearly, I said it was a mistake and this is the first time it happened. It was not intentional.
