'Last night Mr George Ballard of Campden in Gloucestershire, calling upon me, told me that Mr Roger Gale bought Mr Graves’s coins for 21 guineas or 22 pounds one shilling, which he said was a very inconsiderable, trifling sum, in comparison of what they were really worth, and of what they had cost Mr Graves. Indeed I did not know until Mr Ballard told me, that it was so very valuable a Collection; but he assured me that he had very near a perfect series of Roman coins, & many very considerable ones besides, & that he had bought about hundred rare ones a little before he died, so that for ought I know the Collection might be worth 150 guineas'
