Heavy Boots (BREAKthrough) is presently valued at about $0.11 in raw condition. Price action is stable over 7 days, moving only 0.0%.
That is close to the 30-day average of $0.11. The 90-day window shows a floor near $0.10 and a peak around $0.16 (55% total spread), which maps to high-volatility movement.
This version is categorized as Uncommon.
Current valuation lens: Weekly drift is minimal (0.0%), indicating a relatively balanced short-term market. Observed 90-day bounds of $0.10 and $0.16 create a 55% band, matching a high-volatility profile.
Current value remains close to its 30-day mean ($0.11). Without a consistent graded comp in the current snapshot, live listings are still required for reliable condition-based valuation.
