It's not a Proof set, no Proof coins were were struck in 1965-1967. The set is a "Special Mint Set" that has coins with semi-proof like surfaces with less design details. Issue price was $4.00 average retail value is $15.00.

No. The US Mint in San Francisco has produced many coins for circulation since it opened in 1854. Prior to 1968 nearly all proof coins were made at the US Mint in Philadelphia, Pennsylvania. Beginning in 1968, all proof coins were produced at the US Mint in San Francisco although this mint continued to produce Lincoln Cents for circulation until 1974 and Jefferson nickels until 1971. In 1984 the US Mint at West Point, New York began minting proof coins as well. The Philadelphia Mint also produced proof $1 coins in 1999.
The 1981 Proof set has a current value of $9.00 and issue price was $11.00 but check the "S" mint mark on all the coins, on most of the sets the mint mark is filled an does not appear well defined. If all coins have a sharp clear mint mark, value may be $300.00 or so.
Your set is uncirculated but not proof. Proof coins are specially-struck with a mirrorlike finish, and are made only at the San Francisco Mint. The P and D sets are taken from normal circulation strikes. As of 12/2010 its value is about $8.
These coins are no longer in circulation since Irelands changeover to the Euro in 2002. Unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they have little or no value.
These coins are no longer in circulation, but unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth 1 cent.

If you mean a 1990 Silver Eagle only Proof and bullion coins were struck in that year. From 1986 to 1992, proof Silver Eagle coins were minted at San Francisco and these coins bear the "S" mintmark and have a current retail value of $20.00. Bullion Silver Eagle coins dated 1990 were also struck at San Francisco but do not have mintmarks, the value of these coins depends on the spot price of silver at time of sale. As of today it's about $17.50.
Current retail value is $54.00

Assuming the coin's denomination is given in euro cents and not pence, you have a common circulation coin from Ireland. In that case it's not worth any premium. Ireland is part of the eurozone so a euro coin would not have entered circulation any earlier than 2002. If it's not a euro coin, please post a new and separate question with its date.

All Australian 1992 coins are potentially still in circulation so, unless they are a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth whatever is inscribed on them.
