What moves lego & collectible toys prices
LEGO prices are driven by retirement status, sealed versus opened, and completeness. A retired set in a sealed box appreciates for years; the same set built with the box gone can be worth a third of that. Set numbers are the only reliable identifier because names get reused. For vintage toys, original packaging and unpunched cards multiply value. Hot Wheels and Funko prices depend on variant and exclusivity codes.
How to read this
The median is the middle asking price of live Buy It Now listings for this exact search, so it reflects what sellers are asking today, not what buyers paid last month. Use the 25th percentile as a realistic quick-sale price and the 75th as a patient-seller price. Anything listed well under the 25th percentile is worth checking for condition, completeness, and seller feedback before you buy.
