All coins operate through their own blockchain and can be used as a means of payment. Almost all Altcoins are derived from the Bitcoin blockchain. However, some Altcoins have started their own system and blockchain (Ethereum for example).

Tokens are a kind of shares that lie on top of the used blockchain. With the tokens you can prove you as much percent of a specific system or blockchain ownership, that is, a piece of a project or business. Tokens cannot be used for making payments, but can be exchanged (trade) for Altcoins.
