For all of the US coins, look them up in the Guidebook to US Coins. The dollar coins are worth a minimum of $6 each, the Indian cents are anywhere from 25 cents each and up. The penny with 2 of the same sides is a magician’s coin (You always win the flip). As for the foreign coins, unless they are silver they really have no value. If the paper money was wet, from the river, it’s probably in poor shape and not very collectible.
The foreign coin you describe is a bronze Irish penny featuring a hen and chicks. Value depends on amount of wear, its scarcity and the demand for it. There were 17.52 million minted that year of a design used 1928-68. It may be worth from about .10 with heavy wear to around .50 with medium wear to maybe $2 with light wear. If you list the others by Country, Denomination and Date I can give ranges of value for them as well. You might also try a library for a copy of the Standard Catalog of World Coins for more interesting info, pics and values.
The amount the coin may be worth is based on a few factors: The 1943 Cent Truly Being copper specifications below) The U.S. Mint it was struck at. The Condition or grade of the coin. Where and how you sell it.
There are only a few Copper 1943 cents that were made from the coin blanks left from the previous year, that are worth thousands of dollars. In recent years a “1943 S” (San Francisco Mint) copper coin has gone for about $60,000 dollars at auction. I remember the prices from the P (Philadelphia) mint ranging from around $10,000 many years ago to $73,000 in recent times. There are many counterfeits of this coin so get it authenticated.
If you have a copper colored 1943 cent that can stick to a magnet, what I think you may have is a 1943 steel cent that somebody had copper plated, recently I have heard of a lot of these counterfeits surfacing. Since two pieces that sold a year or two ago and made it onto the news.
A real copper 1943cent weighed 3.11 grams, the steel ones in 1943 it weighed 2.7 grams and were zinc plated. From 1944 to 1982 it weighed 3.11 grams and were 95% copper again.
Beware of 1943 coins sprayed with copper or altered dates on the 1948 cents. Since in 1943 they made steel cents. See if it is attracted to a magnet. Many people have cleaned, polished or plated the cents to try to sell them as valuable. They are not at all collectable!
Some outside possibilities are: It is a cent that was plated with some other metal. I have seen Copper, lead, solder, tin zinc or silver. I have even seen cents cleaned in metal cleaners that change their color to copper hues. Most coin shops and all coin Shows Large or small will have people knowledgeable enough to identify this piece for you. These rare coins can, and do, sell for whatever someone is willing to pay at auction.
There is no record of how many 1955 cents were made with this die. Since all cent collectors want one for their collection prices stay high. The sale price also is according to grade. The grading scale goes from 1 to 70. The list price for a grade 40 is about $1,400 dollars but in grade 65 is $37,500 dollars. So the coins have to be examined one at a time to get a market value.
The 1990-cent is a zinc core with a copper plating on it. The mint strikes both sides at one time and the coins image would not be intact if it had not been seated between the dies properly. The plating worn on one part of the coin leads me to believe this.
