How many cards are there playing cards?

In a normal deck of cards there are:

• 4 aces
• 4 twos
• 4 threes
• 4 fours
• 4 fives
• 4 sixes
• 4 sevens
• 4 eights
• 4 nines
• 4 tens
• 4 jacks
• 4 queens
• 4 kings
• 2 jokers

However, each of the 4 cards is either a spade, heart, diamond or club. So there is really only one of each card, such as the 10 of hearts or the seven of spades.
