Nollya Coin still is not listed on centralized exchanges like Binance but you can get Nollya Coin on TokenJar, you will need Metamask if buying from a PC and also some Ethereum in the account.
You can check the current trading price on TokenJar platform.
This is a DEX exchange, it means there is no central servers to process the transactions.
You can sell also NLYA there.
Another choice is Forkdelta, a DEX that is a fork of Etherdelta, it is like TokenJar in some way and you will need also Metamask and Ethereum to buy/sell NLYA.
You can trade here: https://forkdelta.app/#!/trade/0xcee4019fd41ecdc8bae9efdd20510f4b6faa6197-ETH
