2010-S $1 James Buchanan with Signature, DCAM PR69DCAM 认证号24545893, PCGS号417881

2010-S James Buchanan (1857-1861) Presidential Dollar PR69DCAM { PCGS-4 } (Apr'2013) He is the only president from Pennsylvania and the only president who remained a lifelong bachelor. During Pierce's term he served in London as a minister to the Court of St. James' and therefore was not caught up in the crossfire of sectional politics that dominated the country. Buchanan was viewed by many as a compromise between the two sides of the slavery question. Like Pierce, he was considered a "doughface", a northerner with southern sympathies. Buchanan's efforts to maintain peace between the North and the South alienated both sides, and the Southern states declared their secession in the prologue to the American Civil War. Historians have argued that his failure to deal with secession the worst presidential mistake ever made.
