'Since ye sealing of this, I received a letter from one Welborne, who is Steward to ye Earl of Peterburrough; wherein he offers to sale (either to the University or any private person) a Collection of silver and brasse \coyns/, consisting of 13 hundred pieces; but at so dear a rate, (viz. 6s. one with another) that I know ’tis to no purpose to mention it to ye V. Chr [Vice Chancellor], nor in[deed] would the University buy them at any rate. I suppose ’tis ye Collectio[n] of his Master, tho’ he only tels me, they belong to an ancient Gentleman, who is willing to part with them because his Sight begins to grow dimme; an[d] addes there’s a cabinet to be sold with them, so curious that it was design’d to have been presented to K. James as a repository for his Medals. I have heard Beverlandt commend Peterburrough’s coyns as ye best collection in England. This I have added because I know not but Sr Roger may be disposed to purchase such a collection. I suppose for a small gratuity we might have a man of judgement & fidelity to view them; and doubt not but they will abate much of the price he proposes, though he says 30ll. a piece have been offd for so[me]. A Letter may be directed to Mr. Robt Welborne, near The E. of Peterb’s House, by the Horse Ferry in Westminster.'
