The LEGO Acidicus (njo0066) is worth $33.29 used and $70.20 new/sealed on average, based on BrickLink sales data from the last 6 months. Prices range from $10.43 to $60.00 depending on condition. This is above the Ninjago theme average of $8.54. Completeness (all accessories included) and print condition are the biggest factors affecting price.
What sets include the Acidicus minifigure?
Acidicus appears in 1 set: Epic Dragon Battle (9450-1, ~$462.27). Since it was only in one set, it can't be sourced elsewhere — that scarcity is reflected in the price.
How do I identify Acidicus?
Look for the BrickLink ID njo0066 — it's the definitive identifier for this figure. Acidicus is made up of 3 parts (a standard minifigure assembly). 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.
What's the best way to sell Acidicus?
List it individually on BrickLink with the ID njo0066 — buyers search by part number and will find it. Include clear photos showing condition. At $33.29, it's worth the time to list separately rather than bundling. If you have several Ninjago figures, listing them all at once saves on the per-item effort.
Does condition matter for Acidicus?
At $33.29 average, yes. Buyers at this price point expect a complete figure with all accessories, no major scratches on printed elements, and tight joints. Minor play wear is generally acceptable, but cracked or heavily scratched torso prints will drop the price below average. If you have the figure new/sealed (averaging $70.20), keep it protected — the premium for mint condition is significant.
