Those dots are corrosion.:diablo: Spoils an otherwise nice coin.

Those dots are corrosion.:diablo: Spoils an otherwise nice coin.

Owner was told that it was caused by a worn/damaged Die and worth a few $ as a novelty but that's the usual cop-out from a Dealer when they don't know or care.
I'm not so sure with the main dot,i've never seen anything like that formed by corrosion before,solid as and seems similar to the letters underneath both in appearance and texture but i guess there is a greater chance of it being caused by chemical reactions in the metal itself than a pitted Die.

[robbiegal]

give it a bit of a tidy up
if it's corrosion it will peel off and you'll have a nice shiny spot instead!!

Yeah RG,but that big dot over Penny is solid as a rock and genuinely looks part of the Coin,not like the crusty pimples/lumps you get with normal corrosion.
Its not my Coin so kinda restricted on what i can do unfortunately.

[nealeffendi]

I'm confident it is corrosion, I've seen similar lumps on other pennies. Look at the pit on the leg of N, classic corrosion pit.
Also what are the chances that this coin got those lumps from a deteriorating die? We can identify the die and those faults are not known with this die, so unless the die suddenly started pitting in the last .1% of its existence it isn't a die fault.

[Basil]

I'm confident it is corrosion,

No worries,glad to get your opinion,as i said i don't know much about these varieties,for over 40 years the only 1920's i was interested in was those with a Dot over the Top Scroll or Unc.

For anyone hunting for a 1920 dot over bottom scroll with London obverse there's one for sale at the moment: http://www.sterlingcurrency.com.au/items/1920-penny-dot-above-bottom-scroll-london-obverse-fine

[autocoupler]

It was quickly swooped on that's for certain, I remember checking that site in the morning, and it wasn't there I'm sure. That was quite a realistic price IMO.

[Mister T]

Yeah I thought it was well-priced too.
I recall one for sale for $5000 or so a little while ago and it was nicer than that one but still Fine.

[nealeffendi]

It seems to be in a slab (has the 3 bits of edge plastic) but no numerical grade is given. So is it a details/no grade?

Yes its a details coin.

[nealeffendi]

So now 5 with grades, 2 no grades and about 20 raw

[echidna]

One more.
There was another (new) raw example at the Perth Stamp & Coin Show.

Yes its a details coin.

The coin is rotated by about 10%.
Does anyone know if other examples are also rotated.

[nealeffendi]

First I've read about rotated dies. Mine are all normal so a rotated example in such a small mintage would be ER, might even imply the mint struck the coins individually rather than as a production run (as how/why would a die move 10 degrees in striking a few seconds of production?), though if that was the case then why do some show weakness at a section of the rim (and at different sections for the examples with this problem).
