Nuline is a trademark of Wheaton, Millville, NJ. They produced a huge variety of reproduction and commemorative bottles, in a rainbow of colors. I've got a bunch, usually found them for a few $ at flea markets, antique shows, etc.
They were made from about 1967 to around 1974-75. So, yours is a repro. If you google on Nuline or Wheaton, you'll find more info. I need to research the value more myself too - going to have to downsize my collections one of these days.
