Can anyone supply me with a list of coin metal compositions for Irish coins and any other commonly found world coins that melt for more than 2x the face value?

I am compiling a list that I can print out to keep around when I am not around a PC so I can easily keep coins that melt for at least 2x more than their face value

Here is an example of what I have...

Half Dollar 1965-1970 40% Silver
Morgan Dollar 1878-1921 90% Silver
Peace Dollar 1921-1935 90% Silver
Eisenhower Dollar 1971-1976 40% Silver

Irish silver is almost always worth more than "melt". The only circulating silver Irish coins were shillings, florins and halfcrowns pre-1945 (75% silver) and the 10 shilling of 1966 (83% silver). The 10 shillings is the only one that might qualify as "melt value".

Anything else Irish that looks "silvery" is either cupronickel or nickel.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

The Irish Metals
The farthing, halfpenny and penny were struck in bronze at the same standard as the current English coins which were in circulation in Ireland at the time.

The threepence and sixpence were struck in nickel. They were similar in diameter but thicker than the circulating English coins which were of debased (50%) silver.

In 1942 the threepence and sixpence were changed to cupro-nickel which has better wear characteristics than nickel but which discolours more easily.

The shilling, florin and halfcrown were struck in .750 silver alloyed with .250 copper and at the same weight as the circulating English coins which were of debased (50%) silver. The earlier English sterling silver (925/1000) silver coins were still in circulation and remained so until the 1960's. So three standards of silver were in circulation in Ireland in 1928.

The decision to debase the three Irish silver denominations to CuNi was implemented in the coinage act of 1950.

This was realised in 1951 with the issue of a the shilling, florin and halfcrown in cupro-nickel in-line with the English currency which had been similarly debased in 1947.

The 1966 ten shilling piece was made of 833/1000 silver.
