@Tom B are all these still in the capital plastics frames? Do you have pics of them all together in the display?
Currently, these are all in PCGS holders. However, they were all certified prior to the prong style holders, which is why you do not see prongs. Additionally, most were sent in for certification by me and, as such, means that they have had a single owner while certified. Therefore, both the holders and the coins were well cared for and are rather pristine and not banged up, scratched or scuffed to death.
I just keep looking at them LOL! I think your history and back story to how you obtained and how the set evolved is part of the allure of this set.
