How much is one MetaMask?

Excuse me, I'm a bit confused about the question you're asking. MetaMask is a browser extension and mobile app that allows users to interact with decentralized applications, particularly those built on the Ethereum blockchain. It acts as a digital wallet and enables users to store, send, and receive various cryptocurrencies, as well as to manage their Ethereum-based digital identities. As such, MetaMask itself is not a tangible product that can be purchased for a specific price. Instead, it's a free and open-source software that can be downloaded and installed on a user's device. So, the question "How much is one MetaMask?" doesn't quite make sense in this context. However, if you're referring to the cost of the cryptocurrencies you can store in MetaMask, that would depend on the current market value of those specific assets. Can you clarify what you're asking about?
