Dearborn Moderator United States 97084 Posts	Posted 05/28/2023 3:39 pm OMG - really? what do you expect us to do with those images? OK, How about a full coin image, cropper to the edge of the coin and large enough for us to see detail of the coin, not which direction the wood grain of your table is oriented?

mikediamond Pillar of the Community United States 2738 Posts	Posted 05/30/2023 7:10 pm This effect has been called the "starburst effect". Some view it as a form of Die Deterioration. Others see it as a breakdown of some sort of surface coating. It's possible that some starburst coronas are due to the first cause and others to the second cause. Error coin writer and researcher.

Dearborn Moderator United States 97084 Posts	Posted 05/30/2023 8:11 pm Never heard of the 'starburst effect' before, Mike is this the same as 'radial flow lines' or is it a different cause?

Dearborn Moderator United States 97084 Posts	Posted 05/30/2023 8:52 pm I did, I understand berms very well, berms are a piling up of a material - I used to make lots of them when riding my bike in the desert to help me make high angle turns. From what images I could see on the OP's coin, I don't see berms, just the flow lines. My question was to see if what we call 'radial flow lines' is the same as what Mike Diamond called a 'Starburst Effect'. You see I think they could be the same thing as the die wears out and stretches and contracts from the pressure during the strike. Collecting since 1972. Learning from then on "Tell me and I forget.

-makecents- Pillar of the Community United States 8779 Posts	Posted 05/30/2023 10:07 pm I do not think they are. If you read, it says there is not deterioration showing on the coin otherwise, with the berms, the radial flow lines are a direct result of Die Deterioration. The term Mike used is in the berm definition. -makecents- Report this Post to the Staff
-makecents- Pillar of the Community United States 8779 Posts	Posted 05/30/2023 10:31 pm Not sure now. It mentions an either or situation in the definition and then I found this in the link below. A bit of a loose term. -makecents- Report this Post to the Staff
Dearborn Moderator United States 97084 Posts	Posted 05/30/2023 10:52 pm thanks Jon, it uses both terms there (sort of) its all sorts of confusing, ain't it? Collecting since 1972.
