How much are these baseball cards worth?

The late 1980s to mid ninetys topps,fleer,donruss,etc cards were MASS produced. I mean MASS. Its not rare at all to find this set, however there are collectors for them. These cards in their set aren't very high in value, although that particular year is good, considering the rookies. The 88 set is worth what people will pay for them. If your selling, take anything above 25-30 would be good. As for the topps, I reccomend not opening them, as there is no gaurentee as future value. The card market is down right now, so I reccomend holding on to them. Hope this helped-Littlebeast
