Started a custom set about 3 months ago on the collectors society page displaying my better examples of Lincoln doubled die coins. Other than the PCGS MS66+ 1972 DDO the rest are top population coins. The NGC MS66RB 1955 doubled die is 1 of only 2 graded at MS66 by either NGC or PCGS. You can view this set by clicking on the attached link. Enjoy http://coins.www.collectors-society.com/WCM/CoinCustomSetView.aspx?s=15326
