Jaime Hernandez: The 1924-P Lincoln cent is one of the tougher Philadelphia struck wheat cents to find in Uncirculated Red condition. In fact it is the toughest P Mint Mark struck cent from the 1920's.
The 1920-P Lincoln cent is very similar to the 1913-P, 1914-P, 1915-P and 1912-P Lincoln cents in Uncirculated Red condition. They are all some of the toughest Philadelphia struck Lincoln cents in high grade condition.
MS65 Red: There are probably several hundred 1924-P Lincoln cents that survive in MS65 Red condition, so the coin can be found without much trouble.
MS66 Red: In MS66 Red it becomes very difficult to find and there are probably no more than 75 examples that have survived in this condition or higher.
MS67 Red: This is the ultimate grade as there are probably no more than 5 examples that grade this high with none being finer.
