A 1955 US Mint set contained 22 coins. It had 2 coins from each Mint that produced coins for circulation. All US Mint sets from 1947 through 1958 are double sets.
I'm guessing you have some sort of set that was sold as "special collectible coins" with that title. The San Francisco Mint only produced dimes and cents in 1955 and none of them are particularly rare. If the coins are uncirculated, as of 08/2014 the dime might retail for as little as $3.50 or as much as $55.00 depending on quality, while the cent would be anywhere from 35¢ to $7.00. Both ranges are actually less than prices for comparable 1955 coins from the Denver Mint.
The set should have coins from the Denver mint & the Philadelphia mint. 5 from each mint
9 coins: $4708 coins: $170
It would depend upon which 4 coins are in the set.
San Francisco did not start making proof coins until 1968.If you have a Philadelphia proof set from 1955, the following values were provided by member OahuHawaiiThe price varies according to the market.As of 2012-07-25, PCGS lists it as:1955 Proof Set, Box: $1101955 Proof Set, Flat Pack: $160[1955 Mint Set: $175]
You have to set up and account with the mint, it is very easy to do by phone or the web
Special mint sets were produced in 1965, 1966 and 1967. You are probably refering to the uncirculated mint set produced by the mint as a collector set for most years since 1947. The difference between a proof set and a mint set is this; the proof coin is struck with specially prepared dies that are polished and free from nicks and scratches. This gives the coin a mirror like appearance. Coins in a mint set are just everyday coins struck for circulation but are packaged for sale to collectors as examples of the coins minted that year. In 1961 they minted a proof set which consisted of a 5 coin proof set and and a mint set which consisted of two 5 coin uncirculated sets with one from the denver mint and one from the philadelphia mint.
A mint set contains uncirculated coins from a specific mint in a specific year. Proof coins are specially made for collectors, minted with a higher quality finish, even mirror-like on some surfaces. Currently in the U.S., mint sets are available from Philadelphia and Denver, while proof coins are minted in San Francisco.
The 1999 Uncirculated Mint set has 18 coins in it but no silver coins. Retail value $14.00 The 1999s Silver Proof set has 9 coins in it. The half, quarters and dime are 90% silver. retail value $288.00

These coins are potentially still in circulation so, 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 20 cents.
There are two different sets of coins released by the US Mint every year. The uncirculated coin set contains one coin of each denomination from the Philadelphia mint and Denver mint. These are called P-D sets. This set will have twice the number of coins as the proof set for the same year. For 1999, the uncirculated coin set has 18 coins total and is worth $23.00 according to numismedia.com. The proof set for 1999 contains 9 coins and is worth $55.00.
