If the serial number has a letter prefix or suffix, the machine was made in 1900 or after. In this case, the "H" denotes that the sewing machine was made in Elizabeth, New Jersey, and the numbers mean it was made in 1906. The Singer Web site has this information. The worth is very dependent on its condition and its setting.
It was manufactured in 1957 in Great Britain.
