Of all time as it says, or since the year 2000? This list is missing Monorail Transport Base (6991), Airport Shuttle (6399), and UNICEF Van (106). I'm fairly confident there's more. A Galaxy Explorer (928) set, new in the box, sold for over $1,800 on Bricklink in the last six months. Even since 2000, Cloud City (10123) should be included. But it's listed on Brickpicker for less than $150 new. There are a lot of issues with the price guide. UNICEF Van shows it's worth less than $30. Tatooine mini build (CELEB2015) shows more than a couple hundred, but I can buy it now for less than half. Extension Cable (8886) is showing seven bucks new, but twenty used. It also shows $60 when I look at the chart "Set Value Change from Previous Month" (actually, that chart is completely out of whack for any item it seems). Minifigure accessory packs 850449 and 850486 show a value of zero, as well as the three tins from Star Wars Celebration and Comic Con (Mini Slave 1, Luke Skywalker's Landspeeder, and Sith Infiltrator). Additionally, the list has Mr. Gold on it. What about all the exclusive Comic Con minifugures? Aren't those worth enough to be included?
