Class two doubled dies. What causes these?
What causes doubled dies? doubled hub devices on die creation process. Machine Doubling is caused by the machine. but a doubled die comes from a doubled/tripled/quad die process that creates a Doubled Die. so look for the spread/taller/wider devices that are the real doubled dies.

Struck through on zinc cents:
What will a struck through wire of cleaning bristle look like on a zinc coin? the affected are will show no zinc on the plated/incuse area. the opposite side will not show a push out. the strike though will make the incuse mark, but the dies prevent any rise on the opposite area of the coin.

What are the change over years for the 1988 and 1992 cents? RDV-005 was normal for the 1988 cents. some were RDV-006. Same event happened on the 1992 cents with the RDV-007 dies that was to happen on the 1993 cents. (All the 1993 cents including proofs were RDV-007 designs) know the differences will help train your eyes.
http://goccf.com/t/437447#3763347

What does RDV-005 and RDV-006 mean on 1988 cents? they are two different Reverse-Die-Varieties seen on 1988 reverse cents. one is common (RDV-005) and one has a premium for them (RDV-006). know the differences are made easier by the rounded for flat devices on the AME area on the reverse.

Training your eyes to see what you should be looking for.
Why training your eyes are more helpful? Knowing what you are looking for. study the sites to see what is listed, and look for these on that year and years around that year. view each coin was a previous listed coin. what am I seeing?

Devices with a broken post with a filled device.
Broken post? What is that? on closed devices, if the post break off of the die, it can appear that there is no center of the design. with the post broken on a closed device, that area will be shallow/filed/rise above the device. different from a die chip. no premium for these though.

How can you tell a matte proof from a normal strike cent?
How can you tell the differences between a Matte Proof 1910-1916 cents from a normal 1910-1916 cents the matte proofs have a stronger strike because they are struck twice.

Why do devices look different on Struck Through Grease errors?
What are die devices tapered? How does a Grease Fill on a die alter the strike? to allow the coins to not stick onto the dies. grease prevents the strike from happening on a die void. contained grease or oil can stop even a strike from happening. Hydraulic Jacks work on this principle. Contained chamber with added push, lifts even heavy stuff.

Feeder Finger Damage affects what areas on coins?
What areas will you find damage from Feeder Finger Damage? the fields are the first areas affected, then the bottoms of the devices will be affected next. the tops usually are not affected with FFD. dies are just opposite of coins.

Why Does Everyone Think They Have A Doubled Die?
Why Does Everyone Think They Have A Doubled Die? question asked on answered on/and answered on this thread.
http://goccf.com/t/439300#3782155

Mule Coins
What is a Mule Coin? a wrong die that is from another series used.
http://goccf.com/t/439359#3782725

Wider/taller devices, Shorter/narrowed devices? Cause?
Why are some devices looking wider and some looking smaller? wider/taller is from grease prevention of the tops of the devices being block by grease. smaller devices is from the fields being polished off the die, removing the wider parts of the devices and leaving the tops. making the devices smaller in size.
http://goccf.com/t/439335#3782734

DDD? What is that?
DDD? What is is it? stages of die aging. not a premium for the coins, just what is going on with these single squeezed dies with the lower profiles.

Die States, how does it affect coins when your looking to buy a new coin or a replacement coin?
Die wear, does it really affect the looks of coins? Is having an earlier die state more beneficial? knowing the difference will land you are nicer looking coin. I feel sometime in the future, the buying of die states will be important. so train your eyes to find a better die state on your purchases.

How are the DDR on Memorial Cents created on a single hub process die creation. (Class 9 doubled dies)
How do bar cents on the Memorial design happen? misalignment of the hub during the die creation. this is a one step process, but if the alignment is not correct at the beginning of the working hub process, and snaps into the correct alignment, then these DDR's will be created on the die and show up on the struck cents.
http://goccf.com/t/439385#3783468

Why are some coins off center looking on one side of the coin?
What is a MAD coin? How does this happen? miss-alignment of one die will make the obverse/reverse not over the opposite die. thus one side is affected. this can happen on both dies, but the miss alignments will be different than an off center strike. (rare)

What does an inverted "S" mintmark look like?
For what year/denomination? On a cent the 1946 year comes to mind.
The inverted 'S' mintmark on that year was a certain Style that was used on that year:
There were three different styles used that year:

Note the Ball serif style. That is the one that is most know for this issue:

Note the shape on an inverted Ball serif:

Two were know for that year. All the rest were normal. The differences between these two? Location of the mintmark positions. Mintmark locations varied up to 1990. They can be used to identify a certain year variety when a mintmark was used that year. But in 1990 going forward, the mintmarks not hand punched any more. They are on the master hub, so they will all be in the same locations. Some examples didn't have mintmarks, Why? Not sure on some? There are missing mint marks from all three mints. The Cents only had a 'P' mint one year, 2017-P. But all the rest of the cents from Philly didn't have mintmarks except for s special event on 2017-P:

On the 1965-1967 U.S. Coins there were no mintmarks on all denominations. Because of the removal of silver from the coins, they didn't put mintmarks those years to make sure that collectors would hoard these coins as much in order to replace coinage that would be missing because of the removal of silver Silver coinage. Just a little history I've lived through on the events of the 1960's. Hope this answers your question.

Are die cracks collectable coins?
What is a die event? Are they collectable? If so when are they considered as slab item? the most extreme die events could have value if they are limited in number. but most cracked dies are continued to be used.
http://goccf.com/t/439480#3783959

Split plating on coins? Keepers or not?
What causes the zinc cents to develop a sunken area on the fields and designs on the cents? split plating is the opening of the plating that allows the zinc to get oxygen. this starts zinc rot. this a not a collectable, but a death sentence for these coins. so if you are buying a variety coin, make sure the mintmark area is not affected. if so then it can become a problem coin to sell later on.

when buying coins, always look for the problems some coins may have and look for the better die state examples. I feel in the future these will be of more demand than the extreme worn die states.
http://goccf.com/t/439485#3783967

Off color coins: Are they always a good thing?
Does a brown color on a coin mean a good thing for the coin? no. if it is residue from being left outdoors, then it is not a plus. This wear off the coin later on. On a missing clad, the strike can be weaker because of the missing height on the planchet. So look for a red color, not a brown color for the missing clad coins.
