If it's an ERC20 based token you may look for the price either in coinmarketcap (in the markets tab) or checking it manually. Example below how:

1. PRL (oyster pearl) look for the contract address of PRL.
2. Go to https://forkdelta.github.io/#!/trade/ContractAddressHere-ETH.
3. Change the BOLD text of the PRL token.

It should look like this: https://forkdelta.github.io/#!/trade/0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208-ETH

Since PRL is already listed in forkdelta, either way is possible: https://forkdelta.github.io/#!/trade/PRL-ETH
