Blind Policy

by George Manville Fenn

They were “wanted” for the clearing up of the death of their two servants, whose bodies were identified by the domestics brought up from the country house; but the witness particularly sought for was the old housekeeper, who, it was presumed, would be able to give a pretty good account of the doings at the great mansion. But she could not be found, and the suspicion at once arose that she had been murdered by the men who made the attack upon the safe after obtaining leave to go up to town on business.

Search was therefore made in the town mansion, and also in the adjoining house with the curious underground works, but without result, and the disappearance of the old lady’s body added to the mystery.

The family were wanted, too, soon after, upon another charge—that of coining, for upon further investigation of the supposed wealth banked in the strong-room, it was found that the coins were base.

But it required a far more than superficial examination to prove this, official after official from the Mint declaring them to be genuine according to the ordinary tests. Their weight was absolutely correct, the workmanship was perfect, and they gave forth a true ring, but upon every sovereign being broken in half, though there was nothing to see, the coin appearing to be of gold with the proper amount of hardening metal added, the application of the acid test showed that something was wrong.

The examination of the bars of metal supposed to be gold, and discovered in the underground place beneath the old professor’s house, gave the explanation, the two chests delivered by the railway company helping the matter, for after the police had removed a layer or two of old books, they came upon small oaken boxes containing ingots of the base metal used in the manufacture of the coin, these being of an ingeniously compounded alloy, whose constituents, after metallurgical analysis, the Mint authorities kept secret.

Examination of the cellarage proved quite startling, from the perfection of the dies, presses, and rolling mills, all of great power, beautifully made, but of foreign production.

There was a small furnace, too, with crucibles, and other paraphernalia, the most interesting find being the small ribbons of metal from which the round counter-like flats had been punched, and some pieces in a box ready for being pressed.

These last ribbons of metal proved to have been made from the base metal ingots, after the old fashion of producing silver plate—before the introduction of the cheap electro-plating system—by which the pure metal is deposited upon the base.

Old silver-plated goods were made by taking a bar of copper and placing at top and bottom a thin slip of pure silver, which was made to adhere to the copper by heat. Then the silvered copper bar was passed through rolling mills till it was flattened to the necessary thickness, and came out with its due proportion of silver on both sides, ready for working up into shape, with the addition of pure silver finishings to the parts likely to be most worn.

The Clareboroughs’ sovereigns were, then, thus made, careful analysis proving that each ingot of alloy was prepared with the addition of one-half of pure gold, that is to say, one fourth part at top and bottom. This was fixed in the furnace; then the ingots were rolled to the right thickness, the flats punched out, and afterwards passed through the die press, to come out so perfect that for years these coins ran current by thousands, even the banking companies receiving them without demur, and it was not till long after that Chester discovered that his two-hundred-guinea fee was all perfectly base.
