How much is a 1911 Indian head two and one half dollar gold coin worth?

If it's a genuine 1851 Seated Liberty silver dollar, which was the lowest mintage year for that coin, it's easily worth $5,000 in extremely worn condition, and significantly higher in better condition. If your 1851 dollar has an Indian head on the front and says "1 DOLLAR 1851" on the back, then what you have is a Chinese-made novelty coin that's not worth anything
There were no Indian head dollar coins. If your coin is large (about 38 mm) and has the word PEACE on the back, the image on the front is Miss Liberty from the Statue of Liberty. In that case, look for a small S on the back near the word ONE. If there is no letter, the coin is worth about $15. If the S is present, it's worth $15-22 depending on how worn it…
