Hello all,

[IvoR1!]

Hi everyone, My name is Ivo (pronounced Evo) new to this interesting site for coin collecting.
I always had an interest with error coins but never really applied myself to it. Recently retired and I’ve suddenly found it!
I cannot wait to learn all the lingo and terminology. I’m sure I’ll be asking a lot of questions and will appreciate the knowledgeable
responses from the members on this site. My first nubie impression as I start looking more closely at the change I receive is the amount
of errors there seems to be out there. I’ve always been under the impression that the US mints were more thorough in inspecting
for defects and errors. Liked to hear your thoughts, theories and facts on that.
Thanks
Ivo

[MintErrors]

Hello, welcome aboard.
Since 2003 or so, to present, major errors have had a hard time escaping from the mint. It's the excellent quality assurance and controls in place to find the errors and reject them.

About 1990, the US Mint added the mint marks to the master hubs. This eliminated the re-punched mint marks (RPM's). Before 1990, the mint used to hand punch the mint mark into every working die. That was an action that was prone to human error. There were a lot of RPMs in the years 1960 D, 1961D and 1962D.

There are two types of collectibles here.

Varieties and errors. They are two different types of coins, and the veteran coin collectors refer to them as follows;

In this day and age, it takes a lot of patience and luck to find a roll with some winner varieties in them..... notice I said varieties ?

Varieties in this adventure of coin collecting are:
Doubled dies (DDO, DDR)
Re-punched mint marks (RPM's) (D/D, S/S, O/O etc.)
Over mint marks (OMM) (D/S, S/D, O/CC etc.)
Re-punched dates (RPD's) (of same year)
Overdates (two different dates)
Mis-placed dates ( located elsewhere, like near rim)

Just about everything else is an error....
