This popped up as an interesting letter relating to U.S. neutrality during 1916. Here is the presscopy image and an automatically generated transcription.
Subject: Serbian Coinage.
October 3, 1916.
Mr. P. H. Pavlovich,
Royal Consulate General of Serbia,
442 West 22nd St.,
New York City.
Dear Sir,
Referring to your letters of September 13th and 23rd, and to reply thereto from this Bureau dated September 26th, relative to proposed coinage for the Government of Serbia, I beg to advise you that upon consultation with other officials of the Department it was again held that this government should not, on the grounds of neutrality, and for the reason that money is regarded as conditional contraband of war, undertake the execution of the coinage desired.
Regretting our inability to serve you in this case,
I am
Respectfully,
[Signature] F.J.H. vonEngelken
Director of the Mint.
