mgalb Valued Member Canada 78 Posts	Posted 04/02/2022 11:50 am Recently purchased a 1974 unciculated double penny set at an estate auction. It is in a maroon case with black felt like holder for coins. I noticed some toning at the edges coming into the center of the coins. I popped them out of the holder because I wanted to dip them to get the film off. When I took them out the backs of the coins touching the holder were a goreous solid blue on one and a lot of blue on the other. So hard to capture the colour on camera. My question is was I wrong to dip them in the acetone (though it did not do anything to the colour) to have them graded, or would they even grade blue cent coins? The surface of the side that touched the felt-like holder are shiny like a mirror. Would you even bother grading them if they do accept because it is just an uncirculated coin and not the prestige or speciment sets Report this Post to the Staff

DBM Pillar of the Community Canada 9864 Posts	Posted 04/02/2022 12:09 pm They can be graded, but as a rule they are not worth the cost. "Dipping" is not considered cleaning... -from PCGS website Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19155 Posts	Posted 04/02/2022 1:53 pm I like what you have. Acetone was not a bad decision. Grading--like most things in life--'it all depends'. Ask yourself what the purpose of grading through a 3rd party service would be--re-sell, add to personal collection, other? Report this Post to the Staff

silviosi Pillar of the Community Canada 6244 Posts	Posted 04/04/2022 8:04 pm You ask for grading? Answer is not for fake toning coins. I do not answered before, because I have 'it in my head those coins and I want to check my testing database. Your both coins was treated with "tri sulfite of potassium" or commercially say TSP. This color on Cu coins will occur if the solution will be heat to 40-60 deg Celsius. so you buy fake toned coins. Sorry for this reality and for the late answer.

TerryT Pillar of the Community Canada 821 Posts	Posted 04/05/2022 01:43 am Some of the packaging that the Mint used in the 1970's actually caused some coins to change colour. I had sets with red flocking that left a red hue on the coins, as well as pits. Most coins with colour are natural and are not fakes as silviosi always thinks. I've been going over old coins stashed away in a wooden box for over 40 years. I am arranging a set of coloured cents from the 10's of thousands I've gone through over the last 60 years. Below are the 2x2's where I found most of my coloured ones. Silviosi, see the 1963 BU cents in the first photo ? It was put away as 100% red (BU at the time). It's sealed with old cellulose tape which added red to many of the coins in the box. Years ago, many holders had plastics that were not friendly or changed the colour. Here's how it looks 50 years or more later. Your blue ones are 100% legitimate, some of mine from the 40's have blue, and it happens on all monarchs (and silver, not just cents) back to Victoria. Some old and new blue. Edited by TerryT 04/05/2022 02:11 am Report this Post to the Staff
silviosi Pillar of the Community Canada 6244 Posts	Posted 04/05/2022 02:41 am Yes Terry, you are right on what you post. Maybe I address wrong. I address to the photo of full blue, not toning with blue from, you know and I know the old packages with PVC which have some sulfites and phosphorus. Those are other things, and in-doubt are time toning. PS: Sorry come back. I receive in the last time many for certification if are natural or simulate. I can say is somewhere between 50 - 50. this because are very similar. What you post are very nice, I like them. Personally I do not collect because I will live three lives and do not finish all the toning's, but I enjoy to see them. Edited by silviosi 04/05/2022 02:47 am Report this Post to the Staff
