1964 Quarter Pattern - RB-1195, INCO

Coin Details

Description

The RB-1195 experimental quarter represents the final entry in INCO's 1100-series of copper-nickel alloy test strikes, marking the conclusion of this particular alloy family's evaluation. Produced at Medallic Art Company in 1964 using official Washington quarter dies, this piece carries special significance as the endpoint of a systematic alloy progression. The complete 1100-series — from RB-1100 through RB-1195 — documents INCO's exploration of a specific copper-nickel composition range, with each five-number increment representing a deliberate variation in alloy parameters designed to map the performance characteristics of this metallurgical space.

Rarity Notes

Extremely rare. As the final entry in the 1100-series, the RB-1195 composition may be among the scarcest in this sub-family, with survival estimates in single digits.
