Double Die Question?

Hi, I'm Pam, nice to meet you. You're gonna love this community. To answer your question tho. I do inspect every coin, but I am new to this. I do it to learn from what types of circulation damages there are to yes mint errors. I'm still at the crawling stage as a collector.

to CCF. I roll search and I look for known errors and varieties with a jewelers' loupe.

Get a feel for Machine Doubling, too. If every newbie did just a little research beforehand, it would make this forum a little bit more focused (i.e. instead of 50% or more of the replies being "nope, that's Machine Doubling"). I understand there's a LOT of excitement when examining coins for varieties and thinking you've found a doubled die, either known or unknown, just that once you get a feel for it, you'll be able to easily weed out issues that don't increase the value or rarity of a particular coin.

Also, on an academic note, learn about the difference between varieties and errors:

"What is the difference between an "error" and a "variety"?

In simple terms, a variety is created before any coins are struck. The dies themselves
contain a anomaly or abnormality. A doubled die is not created as the coins are struck. A
doubled die is created when the die itself is made. Small dates, Wide AM's, repunched
mintmarks, and over mintmarks are the result of die changes or variations in the die. The
Red Book defines a Die Variety as "any minor alteration in the basic design of a coin".
An error is created as coins are struck. Errors are usually the result of dies being used too
long. When a die is used too long, die cracks, dropped letters, Machine Doubling,
laminations, filled-dies, BIE's, clashed dies and other errors occur. Other forms of errors, like
blank planchets, off-center strikes, chain-strikes, and broadstrikes are the result of the die
not striking the coin correctly. Errors are generally worth less than varieties. The Red Book
defines an error as "a mismade coin not intended for circulation".
Take the 1995 doubled die for instance. It is a die variety because there are thousands that
all contain the same characteristics. If you look at "off-center" cents, there are also
thousands of these, but they do not have the same characteristics?

Varieties are intentional and unintentional changes to dies before coins are struck.

Errors are unintentional mistakes or abnormalities made during striking."

Thanks. That's a lot of info.
