Auction house Christie’s unveiled a Stradivarius violin on Thursday that it said could fetch more than $2 million next week to become the most expensive musical instrument ever sold at auction.

The violin, known as the Hammer, goes on the block in New York on Monday. It was made by Antonio Stradivari in 1707 in Cremona, Italy, and Christie’s estimates its value at $1.5 million to $2.5 million.

The current auction record for a violin belongs to the Lady Tennant, a 1699 Stradivarius that sold for $2.03 million last spring. Private sales have exceeded that price.

The Lady Tennant had a presale estimate of $800,000 to $1.2 million.

“There are certainly grounds for (the Hammer) to realize more than the Lady Tennant,” said Kerry Keane, head of the musical instrument department at Christie’s.

He said unlike the Lady Tennant, the Hammer was made after 1700, during Stradivari’s “golden period,” when he is believed to have made his finest instruments. Also, “appraisers like to err on the conservative side,” Keane said.

Of the more than 1,100 instruments Stradivari is believed to have made, only about 620 violins survive today, he said.
