After looking for information I have found that the RC logo is wrong on the cards, there was no crown used on the logo at the time. Coca Cola had a set out that year and I don't think they would have been to happy with MLB allowing a competitor to release a set at the same time even back in 1981. And then I found this list which may or may not be complete.
