The Droid Developer Kit is not a genuine Lego product, as Lego did not release a set with SKU 9748 in 1999. Lego’s numbering system in 1999 used three or four digits, but set 9748 does not exist in official Lego catalogs or databases. You are likely holding a third-party educational kit or a mislabeled item, so authentication requires verifying the manufacturer’s logo and packaging against known non-Lego brands from that era.
The Droid Developer Kit was released in 1999 by Lego.
The Lego Droid Developer Kit (set 9748) is no longer in print and has been discontinued since its release in 1999. It is not available to buy new from Lego or authorized retailers. Collectors must purchase this set through secondary markets such as eBay or specialized toy resellers.
Examine the ABS plastic for yellowing, which is common in 1999 sets, and check the transparent blue pieces for cloudiness or scratches. Inspect the printed tiles on the droid’s body for rub marks or fading, particularly on high-contact areas like the feet and hands. Verify that all specialized pieces, including the unique head and arm molds, are present and free from stress cracks or broken clips. Finally, assess the condition of the original box and manual, as these significantly impact the value of this early Lego theme release.
