HISTORY AND COMMENTARY
Top position plate blocks are extremely difficult to obtain in Mint N.H. condition with superior centering. We have offered only nine Mint N.H. top position plate blocks since keeping computerized records, and none compare favorably to the example offered here. The Fogelson collection, known for its quality top plate blocks, had one in lightly hinged condition.
