Value for 1977-1979 topps baseball commons.
I need some assistance. I recently returned to the hobby after being gone for over two decades and I'm trying to find out the value for legit centered 1977-1979 topps baseball commons. I'm trying to pick up some and I have no idea what a fair value would be. Most likely I wll not have them graded but if I do someday I'm looking for commons that would most likely receive a PSA 8 or 9 if submitted.
Does anyone know how much they would cost? I looked on EBAY but the commons that are being graded NM-MT are not close to being legit NM-MT cards. As most of you know there's ample printing defects and off centering for most of the cards from these years. My buddy recently opened up two packs from 1977 and he's only sending two cards to PSA for grading. The rest are ungradable cards.
