Papal Carrick

Papal coins from the 17th and 18th centuries often incorporated recycled metals, a practical choice in the Papal States' mints.

I'm not entirely sure about a coin specifically called the "Papal Carrick," as it doesn't appear in standard numismatic references I've consulted over the years. What I do know is that the Papal States produced various copper denominations during that period, likely for everyday use in Rome and surrounding areas; these might include something akin to what you're describing, perhaps a variant of the baiocco or quattrino. Designs typically featured the Pope's arms or a cross, struck on irregular planchets that reflected the era's metallurgy. Mintage figures are hazy, with many records lost to time or upheaval. If it exists as stated, it's probably a minor issue, not the stuff of legends. That said, copper coins from this time can turn up in odd places, like an old well in Umbria—proving that history, like a bad penny, has a way of resurfacing.
