The H on top of the A means that it was manufactured by the Hazel-Atlas Glass Company. The 6i is either the plant location that it was manufactured, or to identify the worker that made the jar. If there are circular scar marks on the bottom,that will tell you it was machine made. If there is a mold seam that runs continuously from the bottom to the top, or if it stops at the shoulder of the jar, it is an original and not a reproduction. The good luck clover jars were available in 3 sizes and are worth about $25-$35 dollars a piece.
