Market outlook
Stable Outlook 3/10
Available tracked sales are too few to establish a reliable rising or declining trend; the reported October 2026 raw sales were close together at $95 and $100.
Next months. Uncertain; the two-sale sample is insufficient to support a confident price forecast.
Long term. Dependent on Sasaki's sustained on-field success and lasting collector demand; no reliable evidence supports a specific long-term price projection.
