The Maryland State Quarter looks like a tower surrounded by two bent and leaning trees with the year 2000 under it.
If the quarter has a picture of George Washington on one side, with the Maryland state capital and phrase "The Old Line State" on the other, then it's a 2000 state quarter, worth exactly 25 cents.
1788 is the year Maryland became a state, and 2000 is the year the quarter was minted. It's worth exactly 25 cents.
The US Mint did not start minting quarter dollars until 1796.

Given that the U.S. Mint didn't begin production of coins until 1793, what you have is a modern state quarter for Georgia, Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, or New York, all of which became states in 1788. The coin is worth 25 cents.
