"Q series" and "Crawford 56/4" don't really make sense together. Q series implies it has a Q symbol, like this coin, whereas Crawford 56/4 is a fully anonymous type, with no symbol. It looks like your coin does have the Q symbol, so the correct type would be Crawford 86A/2
Once again, thanks. I was briefly checking my (uncompiled) reference notes when writing that, and missed it. Always learning Your post reminds me, that I have a lot of (fun)work to do; going over coins of mine that are sitting on the wayside waiting to be properly attributed.
