Post your coins with striations.

I learned about "stria" in geology class and carried over that term to numismatics for our internal records to describe coins at the Authentication Service. After you look up the word, post your coins with stria and striae. We can argue that parallel adjustment marks are striae BUT THEY ALREADY HAVE a specific name (adjustment mark) so they don't belong in this thread. Either do parallel grooves from cleaning or PMD. I only want to see if members can find stria that were on the planchet when it was struck and remained visible on the finished coin.

I'll post an example later. Then we can discuss how they might affect a coin's value.

My finger is on the "Ignore" button and I cannot wait (very ) to add (very ) more useless jokers to my growing list of six.

I don't know if this qualifies but they were certainly not struck out

 

I will volunteer, to help speed things up so you can get on with today's Class.

In the likelihood I am already a member of The Gang Of Six, contact me for suggestions on making it The Gang Of Seven.

Now that is great....!!
I love humor that is appropriate and concise.

 

Do I hear a Gang Of Eight Offer?

 

Actually, I'm pretty sure I was #1.

 

Krap.
I am NEVER 1st!

Edit to add reverse crop

 

Since it is so easy to just not read, why "ignore"?

 

I hope you don't mind if a world coin guy plays along. Not sure if this is what you mean but in my mind it fits the description.

 

Sounds like some kind of bugs.

 

It is!!

First one of these I ever saved. Does it count

 

I think your right

 

Here is my example, showing parallel discoloration marks in the left fields of the reverse. The coin was cleaned, unfortunately, but the marks remained. Would these qualify as striae?

 

Please put me on your ignore list.

 

Nice coin, very interesting to see the really strong lines in it. I like the double die clash too.
