They do look awesome. I wonder what makes a coin go like that?

​Not sure what makes the coin go like that, you can find forums talking about streaky or stripey lustre, most of the answers sound like fantasy rather than fact, think it's something to do with the metal mix but don't quote me on that! 8. .

They are called wood grain. It is an alloy mix I think. Some people love , but some hate. We have talk a lot about these in the forum, should be able to find more about them.
AT THIS TIME IAM NO LONGER SWAPPING. I need too put things in order. And take some time off. Thank you yours daryl

​Thanks ALLRED, did read somewhere they where called wood grain in the US ( makes sense) UK tend to call them streaky or stripey lustre from what I could find, will use the term wood grain from now on, like it!

I like them too. Definitely an alloy mixing issue, tin (and/or zinc) not completely dissolved before rolling.
I have just one, a US cent.

you can see how the streaks are visible right through the planchet.
Bonaparte instituted the setting of merit above birth, and completely stripped the divinity from royalty, whereas crowned heads in Europe were gods before, they are only men now, and can never be gods again, and answerable for their acts.

​Like that, the UK penny is more on the surface, coin on the left and middle picture is the same coin.

Hi lainmac, I am sorry if I came across big headed. Wood grain or stripey lustre. It is all good. Welcome to the site, I am always late. I am thinking zinc has a lot to do with it. You can find it in Zinc coins too

I do love the way it looks.

Hi Daryl, it's all good my friend, you didn't come across as big headed at all, you never stop learning about coins, I've been collecting and selling coins for a long time but there's always something new to find out, Numista is a great site to learn more, even if it appears that newcomers are recycling old posts to gain a bit of knowledge it's all good.

Woodies! I can only suppose that the characteristic streaking wasn't apparent on newly minted coins and only became noticeable once they were exposed to the rigors of circulation.

Not really my thing, I get rid of them as fast as I can. I've always viewed any type of error coins as impaired and usually pretty ugly and the whole thing is lost on me. To each his own I reckon, I have several friends who just love these type of things so I'm happy for them to have them. As some who collects Leper Colony tokens it would be a bit hypocritical of me to question anyone else's collecting ambitions, in fact I'd love to help y'all reach them. If really pressed I guess I could admit to a certain schadenfreude warmth at seeing an embarrassing error from one of the world's premier mints escaping into the wild.

I have noticed that it's not just restricted to badly mixed alloys, it also seems to be only a few series where it occurs. US wheat cents and British KGV farthings and to a much lesser extent Pennies from the same period plus a few wartime zincs are the ones which spring most readily to mind. Has anyone else noticed this?

yes, almost always due to war-time stress.

This is a type of error during production of sheet metal forming for minting of coins, for understanding this you have to understand how coins are minted. Coins are minted from sheets of metal roll. These sheets are made from a large chunk of metal which are rolled in rollers to make it flat sheet to different thickness. During this rolling process the thin layers of metal get pressed one upon another during rolling process - it usually occur in the starting point and end of the sheet. As these are thin layers one upon another pressed by rollers, with time it react with environment more that a single sheet as single sheet has less pores than this layers of sheet due to this coin and appear like a wood finish or lines.

I think it's quite attractive. I understand it's a "flaw", but I kind of just consider another type of toning.

​I Agree, if you set out to deliberately make coins look like this it would be harder to replicate than a normal coin , .. just a thought!

I would think that a term involving lustre would be misleading, because I believe it is an alloy mixing issue--and therefore not just on the surface.

Could KGV pennies have the same problem as U.S. made copper and brass planchets of World War II and shortly afterward--the copper came from recycled artillery shells, which may have had impurities from shellfire?

​exactly. all kinds of 'mongrel' scrap, some less miscible than other.

The last coin (1967), I think that he was made a repatinado with ammonia.
That clearer line in the center may be the one that makes the cord that holds the coin.

Most likely a filled die. It looks too smooth to be the loss of a layer due to lamination.

This particular thread had me trolling eBay, and given I collect Australian coins as well as Third Reich coins, I found and bought this just for the look of it.
