If you collected baseball cards in the 1980s then you should always be ready to have your hopes of riches dashed!
I'm glad I still have the 1981 cello. After letting me open the 1982 Donruss (and yeah, those early Donruss cards were so thin!) my father bought Topps wax boxes in 1983 and 1984 and again wouldn't let me open them. I started collecting myself a few years later and in 1987 my father saw how hot the market was and he told me to open the 1983 and 1984 boxes. I think he was hoping we'd find rookies for Boggs, Gwynn and Mattingly. Complete bust! We didn't get a single rookie card for any of those 3 guys. I wish I'd not opened those. I could have sold the pair now for about $1000 based on recent eBay sales. Instead I have a bunch of raw crap - but it's my raw crap and I've kept them all these years.
Here's the link to the sale on eBay for the Donruss Ruth promo sheets. This seller has sold 11 already and has 6 more on the market:
