You are asking about a British coin dated 1788 ("Georgius 111" refers to King George the Third). You would need to give a better description of the coin (condition and denomination, or at least a physical description of the coin's size, material, design, etc.) to get any kind of an estimation of value - it could be less than a dollar or could be several thousand.
Also, there were many tokens and counterfeits - mostly copper or brass - made around that time period, so your "coin" may fall into one of those categories as well.
