Duplicate cards within a board

[Olivia Williams]

I recently discovered that one of my boards has a large scale of random duplicate cards.  Is there a way to detect duplicates with the board and delete them? 

For example the board is a list of Proscpects so the name for the cards will be Betty Sue and Charlie Stuart, etc, but then when I looked recently there were 2 Betty Sue cards and 2 Charlie Stuart cards even though I don't remember creating two.

 I can't see how I could have accidentally created the duplicates at such a large scale.

If not, is there a way to export the board list?

Thanks!
