"Each Trump Digital Trading Card will have a unique pre-assigned rarity. Think of it as variations or parallels in traditional baseball cards. Some will be one-of-one’s (i.e. the only such copy in the world), while others will be limited to 2, 5, 7, or 10 copies. No Trump Digital Trading Card will have more than 20 copies in existence!

45,000 cards divided by 20 = 2,250

but with some being limited (don't know how many) to 1, 2, 5, etc. I figure around 3,000 unique images.
