Hi

In BTC-e Novacoin is traded for 0.028 BTC but PPCoin is traded for 0.0015

Why NVC is more valuable than PPC, though NVC is newer than PPC and was considered as a scam for a long time!
when we want to talk about it technically, both coins are the same, they support PoW/PoS except that PPC uses SHA and NVC use Scrypt, it's likely that :
PPC = BTC + PoS/PoW
NVC = LTC + PoS/PoW

it looks normal when NVC more valuable as LTC but i think PPC is better than NVC as it uses SHA which is less power consumer ..
