Long-Term Value: 151 vs Prismatic Evolutions vs Black Bolt – Which ETB Will Age Best?

Hi all,

I'm trying to plan a long-term sealed investment and I'm torn between three Elite Trainer Boxes: 151, Prismatic Evolutions and Black Bolt / White Flare

Here’s what I’m currently thinking:

• 151 has nostalgia, Gen 1 fanbase, clean Kanto aesthetic, and strong demand already.
• Prismatic Evolutions is like Evolving Skies, when there are Eevelutions, it's already top.
• Black Bolt might be a sleeper hit. It brings back Gen 5, is said to have limited print runs, includes 800+ cards and introduces the BWR rarity.

I'm thinking Black Bolt might be the most undervalued right now, but I’d love to hear your thoughts.

What do you think will perform best in 5–10 years?
Have any of you invested in sealed ETBs before and seen major gains?

Would love to hear market logic, data, and personal instincts from collectors or investors.

Thanks in advance!
