The Rare 'Holy Grail' Pyrex Print That's Worth Hunting For At Thrift Stores

When you see a Pyrex product at the thrift store, it's worth picking up. It's one of those retro kitchen items that should still have a place in every home. The brand is known for its durable construction and often, its fun colors and patterns — this is especially true for the vintage pieces! While some Pyrex items will simply serve to brighten your refrigerator or lunchbox, others are serious collectors' items, worth thousands of dollars or a prized place on your display shelf if you're a collector yourself.

The most valuable Pyrex pieces for collectors tend to be items that were limited in production, either because they were promotional items, tested in limited markets, or sold as specific pieces rather than full product lines. There's perhaps no better example of this than the piece some collectors refer to as their holy grail: The clover- and heart-covered "Lucky in Love" casserole dish. It's one of the most valuable vintage Pyrex pieces to keep an eye out for while thrifting.

This specific Pyrex print is almost exclusively found on the brand's 1 quart round casserole dish. It came out in 1959, at the end of a decade when Pyrex was experimenting heavily with limited-run, promotional prints like this one. Collectors note that this pattern is so rare, it might even have simply been a test piece. The experimentation is evident in the design, with some pieces featuring hearts that overlap the clovers, while others have hearts that hover neatly above them. Interestingly, the "Lucky in Love" casserole owned by the Corning Museum of Glass — Corning being the parent company of Pyrex — has no hearts at all. Only clovers.

Most folks agree that "Lucky in Love" is not one of Pyrex's most beautiful designs. Instead, it's the rarity of this piece, and it's ephemeral, experimental nature, that make it worth so much to Pyrex enthusiasts. One iteration of the dish sold on eBay for over $22,000 in 2022, so if you find it at the thrift store, regardless of its condition, snap it up immediately. If nothing else, it will make for nostalgic kitchen decor that brings back all the good vibes.
