"AMS" stands for
Asset Marketing Services, a shadowy coin mass-marketing company. I say "shadowy" in the sense that they don't actually trade under their own name anymore. You may have heard of "GovMint.com"? Or maybe "First Federal" or the "New York Mint"? They're all names AMS trades under these days. They aren't a mint nor affiliated with any mint nor any government in any way. So the penny was acquired by AMS from a second-hand source and placed in the AMS wrapper, many years after it was struck, and no doubt on-sold for far more than what it was actually worth.
I should also point out that in 1996, the "large copper penny" enclosed here was not actually legal tender in Ireland anymore. These coins ceased being legal tender in 1971. As for value, the
NGC priceguide (taken from the Krause world coin catalogue) lists it at $1.50 in Unc.
