A 1952 penny with a blank side is considered a mint error, which can significantly increase its value to collectors. The price can vary widely based on the coin's condition and rarity, but such error coins typically sell for anywhere from a few hundred to several thousand dollars. If you have one, it's advisable to get it appraised by a professional numismatist for an accurate valuation.
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.
The coin needs to be seen and weighed, take it to a coin dealer, likely the reverse has been removed by some process out side the Mint.
Something with the heads side on both sides is a post-mint novelty item, and is only worth as much as someone will pay.
The right side
8-18-11>>> All error coins need to be seen for an accurate assessment. Take it to a coin dealer. This may be a fairly uncommon error caused when two planchets (blanks) go into the the coining press at the same time, producing two coins, one with the obverse and one with the reverse. Most of the time this causes damage to the coins because usually it breaks one or both of the dies. Unfortunately most coins like this have been altered out side of the mint. It will have to be weighed and measured to see if it's a genuine mint error. If it's real, value is $10.00 and up depending on condition.
Most likely the reverse side of your coin has been sanded smooth and has no value other than that of the copper in it.
This type of error of misstruck coins is called 'Brockage'. A Lincoln penny with this error is valued at $35.00
A 1964 penny with the head side struck normally and the backside blank is extremely rare and would likely be considered an error coin. Error coins like this can hold significant value to collectors due to their unique nature and scarcity. It is recommended to have the coin authenticated by a professional numismatist to determine its authenticity and value.
A penny that is not stamped on either side is considered a coin blank and does not have the legal tender value of a stamped penny, which is one cent. Its value as a collectible or novelty item may vary, but it typically ranges from a few cents to a few dollars, depending on its rarity and condition. However, it does not hold any official monetary value as currency.
About $30
One side of the penny pictures the Lincon Memorial in Washington D.C. The other side (the side with the person on it) pictures Abraham Lincoln. The penny is pretty much a tribute to Abraham Lincoln
I have many of those I pretty sure it's not a rare find because there are many of them.
This is known as an "unstruck" or "blank" planchet error. With all the pennies that get struck each year, this error is actually relatively common. You can buy these at most coin shows for a dollar or less.
25 cents
The head of a penny is obviously the queens head, and the tail is that thing on the other side of the penny.
A 1961 blank what?????
Your answer depends on the date on the penny.
