You can, my aunt let me look through her pocket change and I found a 1920, 1927, and 1929 penny!
No. They are just more valuable coins. These are the coins from least valuable to most valuable: yellow, red, blue.
1234 coins
Sure, they're valuable. Money is money, regardless the form: paper note or coins.
They're not valuable above face value.
No coins in 1949 are rare, but as with all US coins, high grade Mint State examples can be valuable.
Valuable coins can vary depending on factors like rarity, historical significance, and condition. Some valuable coins include the 1933 Double Eagle, 1804 Silver Dollar, and 1913 Liberty Head Nickel. Trusted dealers like Apmex, SD Bullion, and BOLD Precious Metals offer a wide selection of valuable coins for collectors and investors.
Iridium is a valuable metal and is rarer than gold or platinum. A search of the internet using "iridium coins" should reveal dozens of sites claiming to have the genuine article.
The New Zealand Florin (Two Shillings) was first issued in 1933 and last issued in 1965. The most valuable New Zealand Florin would be 1936 coin. A distant second would be the 1940 and 1946 coins. The 1946 coin with the value shows the kiwi with a flattened back. It should be noted that the valuable coins only have the high value if the coins are in "mint uncirculated" condition.
DO NOT TRY TO CLEAN VALUABLE COINS. The only coins you should try to clean are common-date coins you get in change. Anything you use to clean a coin may make it look shiny for a while, but the cleaning affects its surface in a way that will accelerate the damage later.
No one can answer this question accurately. It depends on the coins!

Coins are certified by services like NGC or PCGS. It is expensive, so it isn't worth it unless the coins are really, really valuable.
