In 1803, the U.S. made the Louisiana Purchase for $15 million. How was this large amount of money transferred before currency was handled as it is today?

This question was sparked by the great question on the purchase of Alaska and I was wondering if there might have been anything different due to it being about 60 years prior. Thanks!

More of course can be said but this was covered by /u/stravadarius in this older thread. Hope that helps!
