2017 Irish 15 Euro

While I'm not entirely certain about a 2017 Irish 15 Euro coin specifically tied to a president's inauguration—given that President Michael D. Higgins was re-elected in 2018—it's possible such a piece exists as part of Ireland's series of commemorative Euros for national events. Ireland's Central Bank has issued silver proofs in odd denominations like 15 Euros since joining the Eurozone, often featuring designs that draw from Celtic motifs or historical figures, which might include presidential themes if aligned with broader celebrations. For instance, the country's coins typically use high-purity silver planchets sourced from European refineries, struck with intricate details that reflect Ireland's heraldic traditions. What I do know is that mintage for these issues can vary widely, and exact numbers for 2017 aren't documented in my records—perhaps lost in bureaucratic reshuffles, as happens. If it does exist, expect it to be a modest silver proof, weighing around 28 grams, with a diameter of 38.61 millimeters, typical for the denomination. No one's perfect at recalling every variant after thirty years, but that's the nature of the hunt.
