As long as it's been done well it won't hurt value. Sloppy workmanship or improperly lidded (for some) can hurt value. A 1950's style of lid on a 1930's lead seam can would be improperly lidded and in many collectors minds, myself included, a devalued can. My personal approach is a re-lid should also have a weight number on top at the least. So what one person finds acceptable may not be to another and hence could reduce value depending on standards.
