Hi there, we can have your bottle of White Horse dated, but not valued. To have it dated, we need you to post photos - let us know if you need help! For a value, try bonhams.com or mctears.com - keep in mind a small fee may be charged. Also, White Horse is a common brand, still available today. Unless you have a limited release, or a pre-prohibition bottle or...from a distillery no longer in operation, there's not much value. Either way, I think it's best to ENJOY what you have
