In 1522, Martin Luther published his translation of the New Testament from Latin into German. Bound copies of the first and second printings were sold for 1 Gulden.
What would that be in terms of today’s money?
I infer a price tag of about $900.
After running out of 5,000 copies in the first and second printings, bound copies from the third printing went for 3 Guldens. I’ll guess that is roughly equivalent to about $2,700 now.
