Thousands of Die Varieties, One System to Catalog Them All

VAM stands for Van Allen-Mallis — Leroy C. Van Allen and A. George Mallis, who created the definitive die variety cataloging system for Morgan dollars (1878-1921) and Peace dollars (1921-1935). Each VAM number identifies a unique die pair based on diagnostic features: doubled dies, repunched dates, repunched mint marks, die cracks, clash marks, and polishing patterns.

The system now documents thousands of distinct die pairs, making VAM collecting one of the most active specialties in American numismatics.
