The value of a 1999 Connecticut state quarter, part of the 50 State Quarters program, typically ranges from 25 cents to a few dollars depending on its condition and whether it is a regular circulation coin or a special edition. If it's in uncirculated condition or a mint state, it could be worth more to collectors. For specific values, it's best to consult a coin pricing guide or a numismatic expert.
The coin usually has the name of the country or ruler on it.
That depends on which country the coin is from.
The Two Shilling (or Florin) coin is a British coin. British coins do not have the country name on them. The Two Shilling (or Florin) coin was also issued by a large number of British Empire/Commonwealth countries, but will have the country name on them somewhere.
It depends on the year and condition, but not much more than 50 cents to $1.50 at best. If it's from the early 1900s, however (1912-1916), it could be worth $20 or more in uncirculated condition (up to $600 if it's a rare 1916 issue!).
