The U.S. Mint said on Tuesday it temporarily sold out of its popular 2015 American Eagle silver bullion coins due to a “significant” increase in demand, the latest sign plunging prices have spurred a resurgence of retail buying.

In a statement sent to its biggest U.S. wholesalers, the Mint said its facility in West Point, New York, continues to produce coins and expects to resume sales in about two weeks.

This is the second time the mint has sold out of silver coins in the past nine months – it ran out of 2014-dated American Eagles in November last year.
