1858 Shilling -- Do I have a variety?

[Generic Lad 25]

Picked up this shilling at my LCS for melt, but looking at it, it looks like both As may be unbarred in BRITANNIAR ? Am I seeing things? Or is this a possibility? I don't have a copy of ESC or anything so unsure if this is a known variety or even a possibility (or if a combination of black tarnish and wear/damage is playing tricks on me!). I tried to take clear pictures with a USB microscope and my phone so hopefully the pics turned out decently enough

It's always possible, but the bars frequently fill on the die, so it may not be what it seems.

I have  a 1857 shilling in much the same condition as yours both A's in Britannia are uncrossed plus one in GRATIA there are also strange blobs growing on some of the letters, I just think it's die wear, neither ESC or Davies list such varieties.

Thanks! I figured it was something like that -- but wanted to double check before tossing it into my pile of scrap silver
