BAD TRADE WITH RAVENCOINS

I may be sounding a little dumb but has anyone tried to trade raven coins. I thought of checking that how many doge and some other coins will I get with raven but when I checked it I saw that for 84 raven I was just getting 17 doge. If you check the price its way below the raven rate. So if anybody can explain why is it so ????? If possible.
