Die events? How are they seen on a coin? Can these be die life ending?
What is a die event? How does it affect the coins struck? die events are what all dies go through during the die aging process. The coins will show this breakdown often by raised areas on the coins struck with a die event that happened. some die event are removed other times the dies are retired. these are common events, kind of like the number of years your count your life with today. birthdays are common, but die events are like life events that affect our lives. so these are not good things for us and dies to go through.

Edges of coins? Why are there type 1 and 2 and how are the reeds formed during the strike?
What are type 1 (blanks) and type 2 (planchets)? Why are reed edges to the silver coinage in the past? blanks are the cut metal, the added upset process adds the proto rim to edge of the blank, making it a planchet. during the striking process, the struck coins will have a plain edge or a reed edge when the planchet fills the collar during the striking of the coin. the collars have the reed edge on the collar that forms the reeds during the strike. (thus some of the business strike coins can have the directions different) But proof dollars will all be in the same direction. Hope this helps everyone.

Where is DDD first noticed on coins?
What is DDD? How are dies affected by this process and how is the damage removed? die wear on the single squeeze dies is different than the die wear of the older style die creation. the die wear showing the fields of the DDD examples and on the older processes, the device design is reduced by the die wear that affects the devices:
Multi-hub processes of the past, affecting the outside edges of devices.

thus you can tell the two different die creation processes. (by the die wear pattern on the outer edges of the devices being affected first)
this affect on the fields of the DDD dies is used to remove these die wear lines on the fields and the removal of Ridge Rings seen on the DDD die coins. This reduction alters the devices size (removing the bases of devices) and sometimes weaken the devices to the point that they are completely removed on the dies. So both Die wear and die abrasion, speeds up the retirement of these dies.

Lighting? What am I doing wrong on micro coin images?
Do you need lots of light when taking micro images? single light sources centered as close over the devices are better. glare is not your friend. too low of a light sources create un-needed distractions. Use the light to enhance and not like a spotlight. you will see more when the lighting is correct.
