I have in my own collection a similar example regarding the A/V. I have described it as follows:
there is a clear and sharp but very thin crossbar to the A, possibly as a result of the A being repaired with an overstruck inverted V punch, leaving the the faintest but sharp remains of the crossbar, similar to the residual 8 of the 1861 F30 6 over 8 (see below under 1861 F30). The cross bar is barely visible in the above photograph but clearly and sharply visible at an angle under a magnifying glass.
