How to define a vintage LP on Audiogon?

Have many mint records I'm wanting to sell and have started listing. For instance I have a Paul Bley recording on the small short lived IAI label released in 1977. Is that considered vintage or simply up to who is listing a record for sale?

i'd define vintage pressings ones released before 70's. vinyls released or re-issued in 2000's and 2010's are called CURRENT PRESSINGS
