Spiderman1804 is Correct.
Sort by Date, is by DAY. it is Not Sort by time to the second.
Cards are Sorted by the DAY they were purchased on
Cards purchased on the Same DAY are then sorted by Card Number
So in the case where you were to have purchased 100 cards on the same day.
these would then be shown in order by Card number for that DAY.
Ascending or Descending order is Followed.
Descending means Newest Day first, then Highest Card Number First
also the Series affects the Order as well.
So It's Day, Series, Number
Where Descending
is Newest Day 1st then
Series letters are I, H, G, F, E, D, C, B, A
Then Card Number Highest to lowest.
Ascending order is
Oldest Day 1st
Then Series A, B, C, D, E, F, G, H, I
Then lower number to Higher Number
