What Drives This Coin's Value
Most coins are common, but the 1986 (BE 2529) date is a key year for collectors due to lower mintage.

Authenticity & Counterfeit Red Flags
Check for magnetic properties (steel versions are magnetic) and crispness of the temple detail.
Notable Varieties & Errors
Small crown vs Large crown varieties in certain years, and the 2529 (1986) year error types or low mintage issues. The reverse features a short or long spire on the temple in some years (notably 2529).
