Are they any error 1952-S pennies?
Other than the usual striking errors that are possible on ANY coin, there is nothing special noted for 1952-S cents.
."The Gift of the Magi" is a famous short story by O. Henry. It also contains an interesting mathematical error in the first paragraph. The author states that Della possesses $1.87 with $0.60 of the total consisting of pennies. The remaining $1.27 is not supposed to have any pennies at all, which is impossible.
When you adjust for inflation what is the worth more 1908 pennies 1960 pennies 1990 pennies 2006 pennies 2007 pennies or any penny melted down and sold as scrap metal?
Yes and no. Yes, they are technically worth about 2.2 cents in copper value (pre-1982 pennies are 95% copper, post-1982 pennies are mostly zinc and are worth about half a cent in zinc scrap) but they are illegal to melt down and as such you will have a hard time finding someone to buy them. 1965 pennies are not rare by any stretch and as such you should just spend it like any other penny…
For any percent error formula: 100 x (Experimental Value - Theoretical Value) / Theoretical Value Take the absolute value of this (make it positive) , and give it a percent sign. Example: The listed mass was 1 gram, and you found it to be .9 grams 100(0.9-1)= -10 -10/1 =-10 -10 becomes 10 10% error You will NEVER have a negative percent error, and its a good idea to write "error" after the percent sign.
