digitalcoin (DGC) - Is still massively undervalued. This coin had a fair launch, unlike similar coins released around the same time. The hash rate has increased considerably recently pending the launch of the CryptoAve exchange. Good dev. and ever increasing community support.
digitalcoin has also been featured on the crypto-trade exchange for quite some time with the other 'big' coins -

http://cryptolife.net/digitalcoin-the-diamond-in-the-rough/Securecoin (SRC) - A CPU
only coin based off Quark, although using Bitcoins economic model, again without a 'pre-mine'. Same great dev. as digitalcoin and this coin is also to feature on CryptoAve at launch.
Take a look at the cryptsy charts for both of these coins - even in turbulent times they have both remained mostly rock solid against BTC and even indicate a potential for an upwards trend with the increasing chance for breakout.
CryptogenicBullion (CGB) - A proof-of-stake coin for the more serious long-term crypto-currency investor. It could start to retrace in value soon.
The usual suspects - Peercoin, Primecoin, Litecoin, Anoncoin.
Perhaps Sexcoin and even Stablecoin are ones to watch this year for some big gains ?

A coin that I find really interesting is Ybcoin (YBC) -
http://www.yuanbaobi.org/Its a scrypt-jane coin with Proof-of-Stake - Its certainly the real 'gold coin'.
Its practically sand-boxed itself in the Chinese market - exchange:
