Pros & cons
What I actually noticed.
LEGO Ideas Dinosaur Fossils
Pros
- Three complete dinosaur skeletons (T. rex, Triceratops, Pteranodon)
- Each on its own wood-look display base — modular and rearrangeable
- Retired since 2021 — secondary market up 60%+ over MSRP
- Skeleton anatomy is surprisingly accurate for a LEGO set
- Best value retired LEGO Ideas set per piece
Cons
- Skeletons are static — no articulation or movable poses
- Aftermarket pricing has crossed into 'wait for a deal' territory
- Display bases are unforgiving if you bump them — skeletons separate easily
LEGO Ideas Seinfeld
Pros
- Iconic Seinfeld apartment — couch, kitchen, breakfast counter, all canonical
- Five minifigures: Jerry, George, Elaine, Kramer, Newman
- Retired since 2023 — secondary market up 100%+
- 30 Rock-perfect kitchen and breakfast bar staging
- Comic books, cereal boxes, and other sitcom accessories included
Cons
- Aftermarket has crossed $160 sealed
- No bedroom or bathroom (just the main living/kitchen area)
- Some interior wall printing is sticker-based
