One cent.It's worth one penny. About 7.26 billion were minted that year.The fact that there's no letter under the date means it was minted at Philadelphia. Even though all other Philadelphia coins started using the P mint mark in 1979 or 1980, the cent was excepted because occasional "short runs" of cents are made at West Point, and the Mint didn't want to create instant rarities.
There's no such coin as a "two cent penny" because a penny is either a 1p British coin, or a 1-cent coin in the US, Canada, and several other countries. If you have a 2-cent piece with a map of Europe on one side and a picture of the Netherlands' queen on the other, it's a common circulation coin worth face value only. If you have anything else, please post a new question with the coin's date.
$400 to $6,000
Not enough information. Post a new question with its date, how worn it is, and whether there is a small S or D under the date.
This coin is pretty much worthless UNLESS you have a doubled die. Get a magnifying glass and look at the date, if you see 1955 punched twice, then post again and i'll look it up for you. A doubled die is worth thousands in excellent condition.
$500-$1500
It is a common date, worth from 3 to 25 cents depending on condition.
This is not enough information to give an accurate value amount. Need to know 'Type' of penny, 'Date' of penny and 'condition' of penny.
If it has one , it's under the date
in the uk penny policy to this date is worth about £7000
If the coin is that worn that the date is illegible, it will be worth nothing.
With a mintage of over 330 million, it's pretty common. If it's circulated, it's generally worth less than a dime. If it's uncirculated, it's worth a quarter, and if it's a proof, it's worth around $18. Also, check the date on the 1955 with no mintmark. If the date appears to be doubled in any way, its worth around $1,100. The coin is so very common circulated coins are 2 cents, one that looks like new is 10 cents.
1¢ Please check your pocket change. Cents minted after 1955, and many before that date, remain in common circulation and are only worth face value.
Please post new question with a date for your " Watergate" penny.
By looking for a date did you know that if a 20p has no date it is worth 5,000
Not particularly - they are worth only a few cents unless in exceptional Uncirculated condition, and even then not more than a dollar or two. The exception to this, however, is the so called "1955 Double Die", in which the date and some other aspects of the front of the coin appear to be doubled. These in Uncirculated condition can be worth thousands of dollars, and are worth hundreds even in circulated condition. See a reputable coin dealer for a better estimate if you have one of these. Note that the doubling on a "Double Die" coin is not subtle - if you're uncertain as to whether or not the date is doubled, it isn't.
