1915 Lincoln Cent. Proof-66+ RB (PCGS). CAC.Plenty of vivid deep orange color remains on both sides of this gorgeous Gem, the surfaces also attractively toned in mottled olive-brown, pale rose and flint gray iridescence. Striking detail is razor sharp throughout the design, the in hand appearance expectably smooth at the assigned grade level. The penultimate issue in the early Proof Lincoln cent series, the 1915 has a mintage of 1,150 pieces. This is the rarest Proof cent of its era after only the classic 1909 V.D.B. and the final year 1916. Specimens that are as smooth and attractive as the present coin are particularly challenging to locate, identifying this as a significant bidding opportunity for the discerning collector. Worthy of the strongest bids.
