Proof or not Proof that is the question ? I have three Nickels that I acquired . One is this 1963 and two 1964 's . All Are very unproblematic an very glossy and appear to have full steps. Do this look proof or Business strike ?
I light candles if you want , got wine ? LOL . Seriously , I only have on a small light source and I already darkened it in editing .
Put a diffuser between your light source and the coin. Oven paper, tracing paper etc. Spreads the light evenly and takes away the glare
