Hi guys! Just wondering if anyone can help me date this jacket and give me an idea of how much it’s worth!

Thank you!

Out of my wheelhouse here, but the ones previous to the 70s I believe say Union Made and Sanforized, the neck tags generally have a lot for text on them - and they seem to be the big earners. I think this is 80s + might get ya in the $100-200 range, but don't quote me ha
