Cards for Dice

Nine cards can be numbered, so that the sum of the
numbers on a randomly chosen pair of cards gives an integer from 2 to 12
with the same frequency of occurence as rolling that sum on two standard
dice. What are the numbers on the nine cards? Are there multiple solutions?
Are there other sets of cards that give the same results?
In a previous POTW
(Alternat
ive Dice),
we showed that we can use multiple sets and choose
1 card from each set (by rolling dice).
Are there any other solutions in which we choose
multiple cards from the set(s), as in the above question?
