If you try to put together an entire series that is stickered, some issues in the set can become obstacles or full-blown roadblocks. I will list a couple business strike half eagles I am well aware of:
1868 $5. PCGS Population: 59. NGC Population: 58. CAC Population: 2. The two CAC grades - a VF35 and an AU50.
1869 $5. PCGS Population: 35. NGC Population: 40. CAC Population: 1. The single CAC grade - AU58.
I own an 1869 (unstickered AU58) and am still looking for an 1868.
I am sure there are other good examples in other series.
