All error coins need to be seen. Take it to a collector or coin dealer.
The US Mint did not start minting quarter dollars until 1796.
In the year 2000, the value of the quarter dollar which is 25 cents was $0.25.
1788 is the year Maryland became a state, and 2000 is the year the quarter was minted. It's worth exactly 25 cents.
The Maryland State Quarter looks like a tower surrounded by two bent and leaning trees with the year 2000 under it.
25 cents
Only state quarters were minted in 2000.
Well, honey, a 1788 Maryland quarter is actually a rarity known as the Maryland Decimal issue, and it can fetch anywhere from a few hundred to a few thousand dollars depending on its condition. But let me tell you, if you've got one lying around, you might want to get it appraised by a professional to get the real scoop on its value. Good luck, sugar!
American quarters have only been struck in 90% silver (up till 1964) and copper-nickel clad metal (1965-present). Canadian quarters have been struck in a 94% steel alloy since 2000. Circulation issues are only worth face value.
All of the "State Quarters" found in change are only face value.
Not gold, and not proof. All proof coins dated 2000 were minted in San Francisco, and the US never struck gold quarters. You almost certainly have a normal Philadelphia quarter that's been plated with a thin layer of gold. The plating makes it an altered coin with no added value.
The one that I am aware of was certified MS65 and sold at auction in 2000 for $47,500.
At present, 25 cents Canadian is worth 24 cents American.
