This is a photograph stating that I have a coin without a grading, and it is the coin below.

As you can clearly see, there is no number in any of the grading squares, but above, can be seen that I have 1 coin.

When I add 1 into the appropriate box, my total rises to 2

If I add the coin within the actual coin page, I still get 1 in a box, but 2 as a total

This is the only error of this type I can find in the whole of my collection
