1951 Irish Proof Set

The 1951 Irish Proof Set stands out for being one of the earliest such issues from the Republic of Ireland, struck just two years after the country declared itself a republic.

These coins were produced at the Royal Mint in London, using high-relief dies that gave them a distinctive, almost glassy surface—planchets likely sourced from standard bullion, not anything exotic. The set includes denominations from the farthing to the halfcrown, all in proof quality, which meant careful striking to highlight fine details like the harp on the reverse. Mintage figures are murky; records from that era weren't always kept meticulously.

One oddity: a few sets turned up with minor toning, probably from improper storage in damp Irish cellars. That's numismatics for you—glossy one day, greenish the next.

We don't know exactly how many were distributed, as sales weren't tracked with the precision we'd expect today.
