I have this 5p coin which after I did some research I find out this can be a Rolling Mill error. I couldn't find too many coins with this error but a couple of old US coins 60's-70's with the stripes at random degrees. This ones seems to very vertical. As I couldn't find too much about this error, I really don't know how to appreciate this coin. I'm a beginner in numismatics, only two months or so and I want to ask how much this coin would worth. I know there is no right answer and it's all about collector appreciation when it comes to price but maybe someone have any clue about this. Thank you.

It is also the full peg variety. On the reverse, on the Irish harp you have two full pegs above the strings. There is also a partial and a no peg variety https://en.numista.com/catalogue/pieces25766.html
Thanks for the tip with variety. Well it seems nobody knows or interesed in this coin so I decided to send it to NGC for grading. They will tell what’s the thing with the coin.
Or they may say nothing about it. I strongly suspect planchet striation lines. And they do appear on the lettering as well, at least on some of them. They aren't as noticeable on the reverse because they happen to coincide with the background lines in the design, but they are visible on some of the devices.
