Observations on the present condition of the current coin of this Kingdom [electronic resource] : With some account of the several ways of diminishing the coin, which have hitherto been discover'd, and the methods made use of to prevent those evils. Particularly, the late evil practice of filing guineas, and the method proposed and approved of by the Lords of His Majesty's Treasury, and the master, warden, &c. of the mint, to prevent the same. Also some farther remarks upon the inconveniences the publick suffer by the deficiency and scarcity of the silver coin, and the currency of foreign money, which the people are imposed upon to receive for more than the real value. By Peter Vallavine, vicar of Mounkton in the Life of Thanet.
