Are there any new coins/under appreciated worth mining?

[helloeverybody]

Im wanting to get back into mining but since i only use a single gpu im wondering if anyone has any recommendations on a new coin or unappreciated coin worth mining where i can get a decent amount of coins that could be worth something in the future. This is a gamble i know but at the current hashrates its pretty much pointless mining xmr or eth so im happy to gamble on something else.  Failing that i will just set up vanitygen and crunch some new addresses
