John Wesley 1784 Letter of orders for Thomas Coke

I have a an original facsimile letter by John Wesley ,1784, Orders for Thomas Coke and for Thomas Owens. I think there are only 5 accounted for out of the original 100 that were printed and brought to America in 1784 to start the Methodist Church in America. received this through family members that date back to Wesley's wife's family. i was wondering if this was highly important and should I have this reframed Thanks Gary
