What is this worth

Hey everyone, I’m not very knowledgeable about coins, but I recently inherited this coin from my dad. I’ve tried doing some research, but the values I’ve found are all over the place some are really high, some are low, and some are practically nothing. I’m feeling pretty lost.

What do you guys think this coin is worth? Also, what are some reliable sources I can use to accurately determine the value of coins moving forward? I’d really appreciate your insight!
