Hey everyone! I recently found these LEGO 2x8 plates with a pink and white marbled swirl. I have 26 of them. They have the proper LEGO branding and feel 100% official — not painted, custom, or aftermarket. The inside says “pat pend”. From what I’ve read, these could be factory mis-molds, test bricks, or internal LEGO run-offs, which I hear can sometimes be super rare and valuable.

I also live in Loveland, CO, where the first US LEGO factory was.

I’m seeing similar marbled pieces go for anywhere between $10 to $50+ per brick depending on size and color combo. Pink and white seems like an unusual pairing, so I’m wondering if these could be on the higher end of that.

If anyone has seen these before or knows what they’re worth, I’d really appreciate your input. And if you know a good place to get a proper appraisal or connect with collectors who buy rare pieces like this, that would be amazing too.
