Exactly how did this error occur at the press?

This should not matter that it is foreign, one peso, as my question is about the minting process. Did another blank get between the obverse die and the initial blank? That's the only way I could think this would happen, but I would love to learn other ways, if any. I have seen these type errors before, but never became interested until I saw this one.

    From your previous post in the world coin forum...

    "I received the coin today and was told wrong. It is 29mm, 8.6 grams with a reeded edge, which makes it a KM460 1 peso coin."

    That type (KM460) should weigh 9.0 grams.

    It’s been machined on the obverse side Dash PMD

    Thanks, Guys. Wouldn't have helped to have asked the weight as the size and edge was misinformation to begin with. Just my luck. But while I am asking the question. Exactly what are the missteps that occur to cause such an error? Just an extra blank die between the obverse die and original blank?

    Seems the only way for that to happen ( inside mint) is to strike two planchets together ( stacked). Thus leaving a blank obverse, and a second coin with a blank reverse.

    Or no ?
