The 40 is VLDS late die state that's had a lot of polishing done on the die has removed details. Now that 61 is interesting. It could be what is known as a "black beauty" annealing error. Or it could be heat-treated to look like one. 55, 58, 59 are known years for them, can't say if 61 is or not. Your pix shows it as a grey/white, is that the true color? BBs are a deep gunmetal grey/black, kinda bluish but with a full luster. You may have one, but the color just looks altered, not a planchet error.
