No difference whatsoever, I think some of the members already discussed this. They might be able to redirect you when they read this. But they are the same cards.
@missingno Thanks. I submitted the 2 cards I mentioned (Porygon and Snorlax) for PSA grading last week. At that time, I thought they were CD promos, so I wrote CD promo in the description.
Is it fine to leave it as it is?
(I am after CD promo holo PSA 10 set, and they are the only two remaining)
You said they came sealed seperately? If so technically it would be incorrect. Since I know these two came sealed along with other cards my OCD would not appreciate it. Although they are the exact same cards.
They were distributed in both ways but are the same card no matter where you got them from, labelling them as a cd promo despite them not being from the cd wouldn’t be too incorrect being as you could get the exact same card from the cd.
