1980s baseball cards worth money are a narrower group than the decade's reputation suggests, and the reason is that production changed enormously inside those ten years. A card from 1981 and a card from 1989 came out of very different print runs, so treating the decade as one thing is the first mistake to avoid.
The early 1980s
Print runs at the start of the decade were larger than the 1970s but far smaller than what followed, and collecting had not yet become an organised activity for most buyers, so cards were handled rather than stored. That combination leaves fewer sharp survivors than people expect, and it is why the early years are worth checking card by card rather than dismissing with the rest of the decade.
The late 1980s
By the end of the decade production had risen to a level that has kept those cards common ever since, and collectors were storing them carefully in boxes and sleeves. High supply plus good condition is the combination that puts a price on the floor and keeps it there. Base cards from those years are generally worth what postage costs and no more.
What is worth pulling from either half
Rookie cards of players whose careers went on to matter, from the earlier years rather than the later ones. Anything that is not a base card. And any card in genuinely sharp condition from the early part of the decade, because sharp examples of even common early cards are less common than the print run alone suggests.
Then price them properly

Questions people ask about 1980s baseball cards worth money
Is a 1980s rookie card worth grading?
Sometimes, when the player matters and the card is genuinely sharp, because a high grade on a card most of whose surviving population is average can move the price a long way. Run it through the uplift calculator before you send it.
Why do people call this the junk wax era?
The phrase refers to the late 1980s and early 1990s, when wax packs were produced in volumes that far exceeded any later demand. It is descriptive rather than pejorative, and it explains why those cards stay cheap.
Are complete 1980s sets worth anything?
Very little for the later years. They were assembled and stored in large numbers and are slow to sell even at low prices.
What about unopened boxes from the 1980s?
