I don't collect bronze, but I think in general, the rule is that the coin is not an error or variety unless there is convincing evidence supporting the claim. Otherwise, the number of imaginary errors / varieties would be huge. So if the letter is supposed to be a V, then it is just a V. The illusion of a crossbar (which is faint and unconvincing) can be caused by say a die crack for instance. If the letter is supposed to be an A, then it is just an A and the faint cross bar could be due to a partial die fill for instance. However, if the variety is documented for that specific coin type, then it is worth investigating more closely. But convincing evidence is still needed.
It's like asking a doctor if a new rash is cancerous. They would say don't be silly as it can be caused by a variety of common things. But if someone has already been diagnosed with cancer and gets a bad rash, then the doctor would work on the assumption that it is related to the cancer if a rash is a possible symptom.
