EBAY is really messing everything up when it comes to getting what the real worth of Elvis stuff goes. I have this hard to find rare, Kissin' Cousins LP mono without the family picture on the cover and someone was selling it for $5.99 I couldn't believe it. So it lowers the value of what you have.
The best way might be to find the sites the sell Elvis items for what it's value and see what they have to offer. I never took the time to look into it. I'm just too busy.
but you do have a rare item, I know what you're talking about.
I found this for LP value they might have a photo section
This is one of them right?
