The power of arbitrage: ask Mr. Pickles

Enthusiasts of frequent-flier mileage have all kinds of crazy strategies for racking up credits, but few have been as quick and easy as turning coins into miles.

At least several hundred mile-junkies discovered that a free shipping offer on presidential and Native American $1 coins, sold at face value by the U.S. Mint, amounted to printing free frequent-flier miles. Mileage lovers ordered more than $1 million in coins until the Mint started identifying them and cutting them off.

Coin buyers charged the purchases, sold in boxes of 250 coins, to a credit card that offers frequent-flier mile awards, then took the shipments straight to the bank. They then used the coins they deposited to pay their credit-card bills. Their only cost: the car trip to make the deposit.

The story is interesting throughout.  There is this (unconfirmed) report:

One FlyerTalker, identified by his online moniker, Mr. Pickles, claims to have bought $800,000 in coins. He posted pictures of the loot on FlyerTalk.

He says his largest single deposit was $70,000 in $1 coins. He used several banks and numerous credit cards. He earned enough miles to put him over two million total at AMR Corp.'s American Airlines, giving him lifetime platinum-elite status — early availability of upgrades for life and other perks on American and its partners around the world. He also pumped miles into his account at UAL Corp.'s United Airlines and points into his Starwood Preferred Guest program account.
