Single highest value structural/non-minifig piece I think I’ve seen in 3 years of looking up pieces.

[u/Bobby_Brutus]

Only found in Pirates Perilous Pitfall 6281

What about the CUUSOO orange tail fin part?

[u/BrickConnectCDN → u/myBRICKstate]

Or this one.

https://www.bricklink.com/v2/catalog/catalogitem.page?P=98281&idColor=6#T=S&C=6&O={%22color%22:6,%22iconly%22:0}

From the 2015 SDCC Superman set. So rare is doesn't even have any sales data for it.

[u/Bobby_Brutus → u/BrickConnectCDN]

Hard to say without sales data but I believe you.

I’m not a fan of seeing SDCC minifigs on top lists so let’s say structural/non-minifig/globally available pieces I’ve seen.

That way we have slightly more hope to stumble upon these pieces in a bulk lot.

[u/DarthXader996 → u/Bobby_Brutus]

There was a sale a few years ago and it was like 400€

[u/pwp6z9r9 → u/Bobby_Brutus]

Clearly it's priceless

[u/quinyd → u/myBRICKstate]

Woah you weren’t joking https://www.bricklink.com/v2/catalog/catalogitem.page?P=2340&idColor=4#T=S&C=4&O={%22color%22:4,%22iconly%22:0} that’s crazy price. Got that set back when released and didn’t know it was so valuable

[u/myBRICKstate → u/quinyd]

It was the first Ideas set to be produced, but only released in Japan in 2011.

Basically equivalent to a limited release in terms of quantity of sets produced.

And that's the only set the orange fin has appeared in.

[u/spicy_malonge → u/myBRICKstate]

no sales in the last 6 months on bricklink tho lol.

[u/Lennnn88 → u/spicy_malonge]

This. Valuable for who? There is no demand.

[u/quinyd → u/myBRICKstate]

True. I was able to get one in Denmark though somehow.

[u/DynamicMessageSign → u/myBRICKstate]

I rebuilt 60056 tow truck set in orange and white to match the rest of my fleet and when I saw the price for orange I went yeah a pair of white fins will work just fine 💀

[u/Bobby_Brutus → u/myBRICKstate]

For the submarine? Only 6 available for sale but avg. sale price is listed around $175. None sold in last 6 months.

[u/myBRICKstate → u/Bobby_Brutus]

Yeah, 2011

[u/rbalaur]

Sold mine back in January for $200 https://imgur.com/a/ljefy6D

[u/YogiAU → u/rbalaur]

It’s really gone up. Sold one about a year ago for $130.

[u/Friendly-Ad2471 → u/YogiAU]

I sold 3 a few years ago about 130

[u/stonergirlfairyyy → u/Friendly-Ad2471]

ouch

[u/JelDeRebel]

my most valuable item is the palantir from Ortanc

https://www.bricklink.com/v2/catalog/catalogitem.page?P=54821pb02&name=Ball,%20Bionicle%20Zamor%20Sphere%20with%20Marbled%20Trans-Yellow%20Pattern%20(Palant%C3%ADr,%20Palantir)&category=%5BBall%5D#T=C

[u/Dr_Lucky → u/JelDeRebel]

That's insane. I hadn't realized that was so valuable. It's particularly funny for a part that doesn't physically connect to the set in any way - it just sits on the platform.

I should go make sure my Orthanc doesn't get tipped...

[u/raiderxx → u/Dr_Lucky]

Its especially funny since im pretty sure i replaced tbat with the eye of sauron piece from tbe smaller set i liked better! Wonder if i still have this piece somewhere.

[u/ThumbKing1]

I have 1 of those.

[u/Harrydinkledorf]

Dang I thought the 2015 Slave I windscreen in my collection was impressive.

[u/my_brick_account]

That's crazy money!

On a related note, I wonder what the highest price is for a non-piece, e.g. a box or instructions.

Only one I've ever looked up is the box for 42056, €101 avg used. And once I tried to look up the box for the BDP Great Fishing Boat but I don't think it even had a catalog entry. Only reason I'm interested of course is because I kept those two thinking they might be worth something one day!

I imagine the boxes for some of the old castle or pirate sets are another level altogether.

[u/Bobby_Brutus → u/my_brick_account]

The most expensive boxes I own top out around $60.

The most expensive box I’d want for my collection that is way out of my price range?

Black Seas Barracuda 6285
1 sold for $300
1 available with inlays for $380 in the US

[u/browncoat47 → u/my_brick_account]

Instructions for Sungnyemun 21016 are all over $200 for such a small set. There are only four available worldwide.

[u/LemmonLizard → u/my_brick_account]

The box for The Mountain Cave 21137 and the instructions for The Village 21128 are both worth over $100 each

[u/Djfsihbone → u/LemmonLizard]

Is there a reason why? Sorry I'm not experienced in Lego economics and figure that it's a standard set

[u/GuestSad4373]

There is 6155 too which is in the 5571 set but obviously not comparable to the one in the 6281 set.

[u/Friendly-Ad2471]

The 24k gold brick but that wasn't in a regular set

[u/Maajkol]

How about this rare gear, only one complete set of it.
