An Irish "Millennium" coin, with a face value of one Irish punt (or "pound"), is worth about US$7.50 in Uncirculated condition and about US$8.50 in Proof.
A 1937 Mercury Head dime is worth about $2.00 just for the silver, the collectible value depends on how much wear the coin has.
In circulated condition it's worth about 25 cents.
Please look at the coin again and post new question. No U.S. $10.00 gold coins exist dated 1937.
Ireland does not use the dollar and never has, so there is no such thing as an Irish 1 dollar coin. Ireland was using the pound in 1952, but there was no 1 pound coin. So whatever coin you have, cannot be either an Irish one dollar coin nor an Irish one pound coin from 1952.
Yes, and no depending on the state of the coin. (clean, shiny, polished)
A 5 cent 1937 buffalo coin is exactly 12,000 dollars in the years through 2010-2025.
The 1937-S Lincoln cent is a common coin. Circulated coins run from 10 cents to about $1.50.
In the grade of EF-40 the coin has a retail value of $3.00.
The value would depend on the year and condition, but most Irish coins aren't worth much unless they're part of a mint set.
It's still worth two pounds, which converts to $3.41 in US dollars (as of 21 July 2014).
