The Small Gear Wheels set, while small, holds some appeal for collectors interested in vintage Technic components. Its low piece count and specialized parts mean it's not a high-value investment, but complete sets in good condition may see some appreciation over time due to its rarity and appeal to Technic enthusiasts. The limited quantity of parts reduces risk, but also caps potential gains.
