Do extra parts add to set's resell value? When I build a set I tend to keep the box and instructions as I noticed they add to the value of the set.
I also keep the extra parts in the box but I'm not so sure if they add actual value. My understanding is they are random so there is no way to confirm they are the original pieces that came with the set.
Is there any value in keeping them along with the set when selling?
UPDATE: Based on the comments I understand the extra parts are consistent and predictable. So I would have thought having extra parts in would make the set more valuable. In BrickLink generally the status of box, minifigs and instructions are mentioned. No mention of extra parts.
Am I correct to think it doesn't add value if we included extra parts?
Thanks.
Generally, I think it doesn't add much value. But it depends.
Some sets, like US version of 8284, have extra parts crucial for alternative model (aka B-model). So unless you include them, you are selling incomplete set. The inclusion of all parts to build all models is part of &quot;complete&quot; condition description on Bricklink. Extra parts excluded though.
Then again, new DOTS sets, which have random printed tiles, but the number of included items is the same. So if you are looking for particular print, it would be nice to have extra.
Sure, there's a ton of sets with quite generic extra pieces, that you may already have a ton of. And buyer may as well already have a lot of them. However, buying a used set with box, instructions, stickers/sticker sheet as well as extra parts is always nice, especially if it is older set.
