Hi and welcome
What this would like to be is a 19th century pattern molded globular bottle. These were made in midwestern glasshouses. One of these in a blue color would be exceedingly rare and valuable.
However, this is a modern remake of such a bottle - it is not particularly old and not as refined as the originals. Sometimes it can be darn difficult to tell whether one is "right" or not...takes some comparative study.
Below is a photo of an original from a recent American Glass Gallery auction.
