The answer to that would be "No!"....Because, it is not a die crack....it is a struck thru string, thread or hair.Are there any other Nightcrawlers with this same die crack?
You could probably get it attributed as such is you mention it on the PCGS order form when/if you decide to send it in for the PCGS restoration service to remove that "spot". Of course you'll also have to pay for the "Mint Error" designation.
Might be worth it, as you'll have the only designated "Mint Error" Nightcrawler. Hopefully, it will upgrade as well from the restoration.
Whether you decide to get it restored or error designated or not....You still own the only known "Stuck Thru Mint Error" Nightcrawler. It's all packed up and will ship out tomorrow.
