[QUOTE="Clawcoins, post: 3333781, member: 77814"]You are totally lumping everything into being an error or variety. A Die is like a car tire. It wears down, as it wears down the tread gets thinner, details get lost, the tread imprint may soften. If a inner belt or something breaks the consistency of the tread can change (get a bulbous area, shift side to side etc. This is Die Deterioration and can create false visual impressions of doubling. REAL Errors/Varieties are due to human intervention. They do something to make the visual change. RPMs is someone stamps the die to make sure the MM's impression is clear, which they could have buffed out when they did maintenance on the die. DD's are an early human problem from not being perfect in their maintenance/ work. So you have WEAR (Die Deterioration) vs HUMAN Intervention (Errors/ Varieties) Hopefully that is understandable.
