Let's assume you're in good terms with the person who gave it to you. You could ask that person about Bitcoin and what the coin means that he or she gave to you.
As you say, you're new to cryptocurrencies. If you want to learn more, there's a lot to learn. You may start here:
https://learnmeabitcoin.com, it's fun there!
If it's a Casascius Coin and stil has the hologram sticker on it, don't peal it. Don't tell anybody and never post or enter a private key anywhere online, even if users here ask for it. A Casascius Coin would've a so-called
minikey under the hologram sticker with which you could redeem it's denomination as long as it's still funded.
But Casascius Coins that are still funded are quite valuable. The gifter would be quite a generous person to you.
Relax and welcome to the forum and your journey in Bitcoin land. Whatever you got as physical token from whoever, don't do stupid things but rather embrace a whole new thing for you. I don't quite see an urge to get in some hurry. Read, learn and hopefully love
BTC!
