JohnWayne007 Pillar of the Community Canada 1187 Posts	Posted 04/30/2021 5:39 pm For the past couple of weeks I had been looking at this set in the display case at my local post office debating on if I should buy it or not. Today I finally did and when I got home and started checking out some rolls I picked up from the bank I decided to put the set under the microscope as well. When I opened the cardboard flip the set sits in, I noticed the obverse on the 50 cent piece looked like it had some grease residue on the obverse, under the microscope I then noticed that it looks like it is embedded into the coin with very small ridges around the grease. I looked online to see if this type of error could happen and it turns out that apparently it can. My question for the error folk that are familiar with this type of error, is it what I think it is? The coin is still in the original packaging, so I went further and decided to try to "Smudge" the grease by lightly using my nail and seeing if it could move around while still being in the package but it did not budge at all. PS the weird look on the bottom left of the Obverse on the full photo is just the cellophane wrinkled from trying to push the grease around.

JimmyD Bedrock of the Community Canada 21860 Posts	Posted 05/01/2021 10:42 am It doesn't look like grease but not sure what it is. Possibly something spilled on it before it got packaged. Is that the same substance at the bottom of the reverse? Report this Post to the Staff
JohnWayne007 Pillar of the Community Canada 1187 Posts	Posted 05/01/2021 11:00 am JimmyD, I have seen hardened grease look similar on a coin so thats just what I was comparing it to. In some areas there are little tiny pits that are rough with no grease/substance, so if I picked off some of the grease/substance (i dont plan to) I'm fairly certain there will be a rough surface with a minor indentation similar to what you find on a strike through. As for the reverse on the bottom thats just my phones reflection Finding and discovering modern Canadian doubled die varieties since 2018. 2023 Recent Publications: Modern Canadian Doubled Die Varieties - First Edition PDF & Paperback https://www.mcddv.ca - (New Site, Second Edition, Registry & Services coming fall 2026) Report this Post to the Staff
silviosi Pillar of the Community Canada 6244 Posts	Posted 05/02/2021 10:26 pm This seem to be some grease from rolling and with annealing will look like this. The question will be we can say it is a planchet or normal process default? Report this Post to the Staff

Back to coins, I have a 2021 with what I just called a plating error. Is that all yours is?

SP67 Valued Member Canada 235 Posts	Posted 05/03/2021 4:30 pm Recently I found similar coin with a clear strike through grease and with some black residue. The following image is a 5 cents 2020. We see some black spots at a couple location including the top of the beads. I found few other coins similar to that one. Report this Post to the Staff
SPP-Ottawa Moderator Canada 10473 Posts	Posted 05/03/2021 6:20 pm Looks like a bit of grease, but not enough to plug the dies or obscure the devices. So to a regular collector, it is a defective strike, and to an error collector, it is not defective enough... These are the kind of coins I use as "bonus coins" when ebay buyers purchase multiple error coins from me... not worth selling, but interesting enough not to send to the bank.
