These are from an Amazon seller (search "graded sports card display") and they're great quality. I'd like a few more to house the pro Longhorns collection (which would need about two of these displays).
And I'm the same way, too sentimental for my own good. Most of these cards take be back to the precise moment in time when I got them and I can still feel that little twinge of excitement when 10-year-old Boom managed to snag them. I mowed lawns all summer for that 1985 Mark McGwire Topps Olympic Team rookie, which I got at a flea market on Harwin in Houston - (Funny-to-me story, when I was little I was the biggest Charlie Hustle fan there was, and though I never got his rookie, I was able to get his 2nd year card which was the prize of my collection for the longest. Then the betting thing happened and I had a "say it ain't so, Joe" moment and turned my back. So, I needed to find a new hero. While thumbing through my cousin's 1987 Topps collection, which is one of the ugliest designs in the modern era mind, I came across a visually stunning card that stood out like a sore thumb. It was of this massive dude wearing green, set against the green A's logo, which popped on that otherwise drab wooden design. I flipped the card over and the factoid was about this guy belting 49 homers as a rookie, an MLB record. Forty-nine homers as a rookie! Well that cinched it, I found my replacement for Pete Rose. This was just in time to catch the Bash Brothers era which began in earnest the next year so things were rosy after all. The moral of this story is I am shit at picking heroes.)
