Oh, my God, you're ALL at it! Even Rob with his C1 halfcrown micro-varieties, if I remember rightly! I only ever recall Richard in denial of this micro-disease! Once I have the entire G5 set, I too will likely seek out the micros, and add the occasional proof coin as and when they appear! Having said that, I do have the flat AND hollow neck farthings! That's a means to an end because I'm looking for die sequences, and the the underlying erased detail holds the key.
