coop Bedrock of the Community United States 62064 Posts	Posted 12/16/2022 2:06 pm Die cracks and chips Why do die cracks rise above the design on coins? the splitting of the die when it cracks, leaves a gag on the die. this void then is shown as a raised line on a die. http://goccf.com/t/436794#3755792 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 12/17/2022 3:02 pm How to Identify the 1982 zinc cent DDR-001 from a normal coin? How to tell a 1982 FS-1801 from a normal die? note the devices are wider on the DDR. look for spread on the devices, not incuse reduction of the device sizes. http://goccf.com/t/436816#3756354 Wheat cent die clashes What do Wheat cent die clashes look like on the obverse of the coins? the outlines of the fields and some devices would be seen on the field areas only. Incuse marks on the tops of devices are coin transfers from other coins. http://goccf.com/t/436882#3756929 Edited by coop 12/18/2022 12:26 pm Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 12/20/2022 12:28 pm Lincoln Cent Series 6 & 9's: Die chips or broken die posts on the 6 & 9's on the Lincoln Cent series? "they aren't closed on this series." http://goccf.com/t/436948#3758214 Grease fill of poor movement of planchet metal? (Often seen on Memorial cents) Grease fill or lower weight planchet issue?

coop Bedrock of the Community United States 62064 Posts	Posted 12/22/2022 2:39 pm 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. http://goccf.com/t/437107#3759493 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 12/24/2022 2:35 pm 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. http://goccf.com/t/437210#3760590 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 01/02/2023 6:18 pm 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.

coop Bedrock of the Community United States 62064 Posts	Posted 01/19/2023 12:10 pm 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? http://goccf.com/t/438674#3776263 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 01/21/2023 1:33 pm 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. http://goccf.com/t/438854#3777748 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 01/22/2023 2:17 pm How can you tell a matte proof from a normal strike cent?

coop Bedrock of the Community United States 62064 Posts	Posted 01/23/2023 1:52 pm 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. http://goccf.com/t/438986#3779127 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. http://goccf.com/t/438981#3779138 Edited by coop 01/23/2023 2:13 pm Report this Post to the Staff
