You are welcome to send in card information voluntarily however as part of the service this is not required.
I am a seasoned card collector and either know the cards you are sending or have the means to find the information.
If by chance I cannot identify your card/s I will contact you, but one of the time-saving features of this service is you do not need to spend a vasts amount of time, detailing cards for me.
Important To Note – any cards that are wrongly labeled are sent back to PSA at my own cost.
