Opinions on this situation? PCGS modifies attribution on a coin graded years ago - 05/26 update
Would love to hear this forum's opinion on a situation I'm navigating through right now.
I'm a variety collector for a world coin series and have been responsible for submitting and certifying unique varieties in my highly specialized area of collecting. A number of years ago, PCGS certified an unique overdate. I've acquired the coin because it also became a required slot in a number of variety sets. PCGS apparently shares coinfacts images with researchers and I was pleasantly surprised to find this coin, along with a number of others in my collection (mentioned as "Courtesy of PCGS"), become plates in a recently published definitive work on the series. It took me about 3 years to be able to find another example of this die pair in a nicer grade, which I promptly submitted to PCGS under the existing variety coin number with variety attribution fee included. The newly submitted coin graded AU53, as expected, however the coin number assigned was that of a non-variety date. Didn't think much of it until I noticed a change to my registry sets. To my surprise, the original VF35 coin was also changed to point to a non-variety PCGS number.
I've reached out to Customer Support to understand the change and was informed that the original coin's label is a "mechanical error" and to send it in to be corrected. When asking to confirm with world graders which reference is used for variety attribution in this series, I was told the Red book. At this point I realized that the customer service agent was probably not used to deal with a situation of this complexity and asked to have the ticket escalated. As per the process, i'm sure I will get a call from a supervisor in the next few days and hopefully get to some kind of resolution.
While I work through the process, would love to hear your thoughts on this. This is the first time something like this happened to me and I find myself unsure about where the responsibility lies. By the way, the customer service rep mentioned they feel that PCGS bears no financial obligation for the overnight drop in rarity and value and that since it was my decision to purchase the coin they are not responsible for the value I placed on it at the time of purchase.
Also, the variety slot in a number of registry sets is still there, which at present makes it an impossible set to finish since the original coin was responsible for its creation.
