THE 5c RETOUCH
There is a positional variety on Row 1/8. It would appear that the top left value tablet was accidentally left blank and a new value was engraved by hand. This retouch appears on all printings of the single plate printings of the 5c value. In the variety, the five is made up of vertical lines whereas normally it has a smooth impression.
