Using a cache of uncirculated 1909 cents and the latest inspection equipment Mr. Tew and his team discovered new varieties of the 1909 cent and a 1910 with a 1909 reverse!
Well researched, the book includes correspondence between Charles Barber & VDB covering classic manufacturing Vs. design issues that likely drove die changes that improved die life. Excellent descriptions and photography simplify identifying the different reverses & doubled dies.
Can't wait to dig out some 1909 pennies to test out my new knowledge! Happy 1909 hunting!
