Extremely rare. This variety has a Type 1 reverse with a misshapen Earth, raised islands off the tip of Florida, and jagged crater lines. On very few Proofs (silver) of 1971-S, the Type 1 reverse artwork intended for the 40% silver Uncirculated coinage was used. Notably, the islands are raised and well formed, not incuse as on the intended Type 2 reverse.
