Dated 1823 seal bottle...magnum size Gardner collection For Sale

Nice bottle that I believe is American based on the construction. It is 11 and 1/2 inches tall by 5 and 1/2 inches in diameter. It has a Gardner tag on the bottom but the sale label fell off years ago. NO damage....looks mint to the naked eye, but bottle was not cleaned before I took the pics. A truly rare bottle in the best of shape. Color of glass is very dark olive green. Has a large sticky pontil on the bottom
