Whatever it is, this is the same I think. If the link doesn't work, search the forum on "odd 1942 Cent". I still have this one. https://goccf.com/t/108894 |

Great thread, Small cent guy, very interesting effect, on pennies, I wonder if anyone`s ever seen that on larger denomination? Thanks guys, for all your input!

Perhaps the coin suffered more than a single indignity.
The pinkish colour, and lack of patina, especially prominent in the obverse pic, sure makes the coin look like it was freshly treated to an acid bath.

SPP Ottawa, could you please elaborate on why you dismiss this coin so fast? Because there is nothing on the dies that even comes close to that pattern, and most certainly is not a strike-though (strike-through on both sides are uncommon, except maybe for grease/oil). The rippled effect you get from a capped die strike is complete different... I have lots of examples of coins like this, seen lots of examples... it can be created by a harshly whizzing brush, or even a blow torch. A few more examples: https://goccf.com/t/110075https://goccf.com/t/256030https://goccf.com/t/227316Mike Diamond also provided a similar explanation here, and other members have posted their extreme examples in that thread: https://goccf.com/t/68438Quote:
This coin was altered outside the Mint. Exactly how it's done is subject to debate. Traditionally it's been linked to the use of a rotating brush. Two points here: 1. Collecting coin errors means embarking upon research to do so successfully. Did you even try to use the CCF search engines to research your question? Several people gave you the answer, but that does not mean we need to do your homework... 2. Instead of trying to figure out what this is, try to imagine the coin striking process, and how something like this could happen to a normal planchet, struck by high pressure dies within the striking chamber. If you can't then chances are it is not a legit striking error.

Well, you are the experts, and did not intend on causing any trouble, I just wanted a little more explanation. You all have your opinions, which I respect, but I have mine.What would this world be if everyone agreed with everyone? Sorry, I`m still not convinced by the explanations given on the coin! I just cant see a grinder, wire brush, acid, or even a blowtorch do whats on my coin, not good enough. All your examples are NOT a match to my coin.the only examples that match, are Small cent guy`s , and the 1957 rippled penny on Coins and Canada.Thanks for your input.

There is a reason this coin sold for a very low price

Kool Kat, what do you think the error is? how do you think this was caused? SPP makes one perfect point, how could your coin come out of the die press like that?
the divets (craters) on the coin do not match up with anything on the die surface.
the only thing this could be struck through is a wet sponge.

I agree its not a blow torch wire brush or acid. If it was struck through anything then I would say..not a sponge but hydraulic fluid. The high grade fluid used in a press is capable of moving metal as it tries to escape the force of the strike. Frankly hydraulic fluid is seldom if ever mentioned on error websites and I'm not sure why as its in every press and a leak would easily cover both dies if leaking from above the hammer. Now I'm ready for my CCF floggin..  ..have at er. |

@ Alexer
Coin presses of the day were mechanical knuckle-joint presses with mechanical and/or pneumatic accessories
Most coin presses today are still knuckle joint but hydraulic accessories are available

Well generally speaking DBM what if a planchet already had something like that on it before it entered the striking chamber, what would it look like?..not like a grease strike thats for sure. Don't get me wrong my first observation I thought PMD too as we have seen these here before...just trying to figure it out thats all. |

What about sheet plastic? what would that look like? I think there`s a third alternative here. Some other substance, that has not been mentioned yet.could very well be hydraulic fluid, if not, no harm done in trying to re-check all the alternatives, if any on this issue. Thank you DBM, Alexer and SPP Ottawa, for this chance to plead my case on this item. I wish I could experiment with a coin press! I will post the weight, on a follow up, Thanks again guys!

The obverse was brushed with a Drexel from left to right. The reverse is vertically. Look how metal is moved to the right on the obverse. Almost no distortion on left with extreme movement on right. Cloth brush.

After 2 hours of tedious blow torch experimenting and 20 min of trying the different wire brush wheels I have (brass and steel), and watching many videos on how acid reacts to different metals (mostly copper) IMHO its not any of those.
And please explain how a rotating wheel\brush can create doubling,tripling and more, it doesn't IMO, but if it did could someone show us an example?
However I do know that this could be done by using an acid etching method I seen in a video, although it would be really tough to do and require a lot of talent (like a trendy hobo nickel talent) and I don't believe this to be the case.
I would like to point out that most of these coins all have the same look. Why would that be?
This happened to both sides of the coin without ruining the opposite sides. I think it happened all at once.

Looks like someone took a brand new 1961 cent and treated it to an acid trip and / or a mechanical touch up with a grinding tool Whatever , it never left the Royal Canadian Mint that way. As SPP stated it should be a tad light in weight. Most assuredly nothing but PMD. There are excellent research articles and books available on the subject of Coin errors. Also if you do not believe any of the experts on here you can always pay some money and send it to CCCS or one of the major US TPG. They are all going to give you the answer you still do not want to hear. A lot of us experimented with coins when we were younger . Lots of fun . Rock Tumblers , hammers , Mercury , shears, acids , Coca Cola, vises , shop class, drills, electricity , railroad tracks. Just some of the weapons of choice to destroy perfectly normal coins and make them errors. Enjoy the hobby and let us know how you make out with certifying your "error " cent . |
