nearly all the altcoins have copied bitcoin one way or another so they all have all bitcoin's features including its block reward halving. you have to be more specific about your second part of the question if you want any particular coin that has halving.
if you are looking for halvings from a speculative perspective then you must know that most of the times there is no price rise in altcoins that have a halving because they get dumped by the miners because of the halving and can't get hyped up either.
I really wonder why most people are always eager to see halving of coins as if it will reward everyone generally and make their investment multi-ply beyond imagination, I dont still understand the concept of it making the price of the coin hike when all we need for a coin to shoot up is either adoption, new investors or whales pump.
Seems to me that halving benefits more of miners than investors. If miners dump the coin, then it will affect investors more. Well, I dont so much rely on the halving that much, except there will be a coincidence and maybe another factor will come then that will turn market around. In
