I just ordered the print version and the epub version.... I'll wait to thumb through the print version but did notice in the epub version a reference to an 1860 F/P HALP penny... That should be 1861..... for the record, but not vital to the book, it exists with both obverse 6 & obverse 7th. Also the display of the epub file on my samsung 3 tablet, 7 inch, when using aldiko reader,is viewed properly only when held horizontally....... looks excellent though and the electonic version will be handy, having it with me... and the hardcopy for permanent reference. ?
