Die Cracks On The Mid 20th Century Mexican Peso?

The position of the crack on a collared press is fine in my opinion. I have seen many pesos with similar cracks. Starting in 1898 collared presses were employed for the new Pesos. Cracks of this type showed up immediately. The 1945 peso was a high production coin so dies may have had their lives extended a bit to meet production quotas. The cracks are fairly new and small. I see no evidence of displacement - which is terminal state. A die in this state could make anywhere from a handful to a few thousand impressions before a die break occurs.
