The current value for a new and sealed Ultimate Builders Set is estimated around $665 today with current average yearly gain of about 11% but will level off in the next year closer to a 8% annual growth. The current used prices for Ultimate Builders Set can be found in the range of $49 and $60 depending on the set's condition, with an average price of $50 if it is in good overall condition.
Ultimate Builders Set is an extremely old and very rare LEGO set. We have not seen set 3800-1 currently for sale online or in the hundreds of retail stores in good/new condition in over 1,252 days. Because of the rarity of this hard to find set the current estimated value of $665.47 might actually be much lower than the true value, assuming this set can be found for sale.
