Guitars

Anybody know what my 1970 Les Paul Custom Black Beauty would be worth? It has gold hardware and is the 2 pickup model. It is 100% original, neck and frets are great. Finish has wear and is dull. I also have a 1953 Gold top that is a refin and has been converted to humbuckers and the new style bridge. The refin was done by Ronnie Griffin of Griffin guitars and it was a year long project. The real period material paint was used. It's a beautiful player and great conversation piece, but I have no idea what to insure it for. Last but not least a San Dimas Custom Jackson DNKY single pu Koa neck, mint cond, black with skull and hangmans noose. This was not off the shelf but back when they were custom only.
