Professor E. Gadd (mar0109) is a common Super Mario minifigure, averaging $4.64 on BrickLink. At this price point it's usually not worth listing individually. Bundle it with other Super Mario figures or include it in a themed minifig lot to move it. The value is in volume, not the single sale.
The LEGO Professor E. Gadd (mar0109) is worth $4.64 used and $6.61 new/sealed on average, based on BrickLink sales data from the last 6 months. Prices range from $2.50 to $6.26 depending on condition. Completeness (all accessories included) and print condition are the biggest factors affecting price.
Professor E. Gadd appears in 1 set: Lab and Poltergust - Expansion Set (71397-1, ~$72.98). Since it was only in one set, it can't be sourced elsewhere. That scarcity is reflected in the price.
Look for the BrickLink ID mar0109. It's the definitive identifier for this figure. Professor E. Gadd is made up of 13 parts including specialized accessories. The parts breakdown on this page shows each component with colors. If you have a loose figure and aren't sure what it is, the brick'em scanner can identify it from a photo in a few seconds.
At this price point, the most efficient approach is to bundle it with other Super Mario minifigures in a lot rather than listing individually. On BrickLink, you can list it as part of a themed minifig bundle. On eBay or Mercari, a "LEGO Super Mario Minifigure Lot" listing with 5-10 figures will move faster and earn more than individual sales.
