You have done some good research on this piece.
Your bottle was made in what I call the US golden era of decanter marketing in the 1950s / 60s. Such bottles are fairly common. Some, such as the highly decorative "I Dream of Jeannie" decanters fetch a decent dollar. Others are are more plain, not so much.
If you scan through the sold listings on eBay, you will get an idea of where value is at. Search for something like "federal law forbids decanter"
