Sounds like we were in the same era. I recall the good vinyl...then came the Columbia Record Club, twelve records for a dollar and the much lower quality presses.
If you cant tell the difference by feel or one look, then stick to paying for cd's. Because you'll get ripped off buying " vinyl" thats the cheaper poly sooner or later, and polystyrene doesn't sound as good as vinyl or last as long.
