Publishing the Principia

Question

It is well-known that Newton's Principia was published by Halley at his own expense, and the story of writing, editing, printing, correction and proofreading is well described in Newton's biographies. However I cannot find some important details:

1. How many copies of the first edition were printed?

2. For what price they were sold?

3. Did Halley get the proceeds from the sales? If not, who did? Newton? Royal Society?

Can anyone help me to find this information?

EDIT. Since I asked this question, I found some relevant information in the article of B. Cohen, supplementing my own copy of Principia (1999 English translation:-)

A. N. Munby estimated the size of the first edition at some 300 or 400 copies, but the number has recently been increased to perhaps 500. Whiteside recons that granting this larger size of the edition, Halley would not have suffered financially by paying the printing costs and would even have made not less than 10 pounds in pocket for all his time and trouble.

Answer 1

Some info from :

• I.B. Cohen, Introduction to Newton's Principia, 1978, page 138 :

No one knows for certain just how large the edition of the Principia was. Rouse Ball reckoned it to be some 250 copies [Ball (1893), Essay, p.67], but A.N.L.Munby held it to be more nearly 300-400 [Munby (1952), "Distribution of the first edition", p.37].

The price to the trade was to be 6 shillings in quires (or sheets) (reduced to 5 shillings if payment was in cash or "at some short time"), but 9 shillings "bound in Calves leather or lettred".
