Bowtie,
Welcome, welcome to the forum. You're in good company here with lots of experts on vintage drums. Your dad left you an incredible part of his youth when you discovered this set in storage, and I know you realize its value goes way beyond the evaluated monetary value anyone can put on it.
I hope you heed our experts' advice in this thread. Several things mentioned already should be re-emphasized:
1. Do not attempt to make repairs or clean these drums without asking for advice first. Simple amateur mistakes like scrubbing the chrome or cymbals with steel wool can result in serious damage, and certain commercial cleaning products can react negatively and damage the sparkle wrap.
2. Do not be tempted to start selling off individual pieces despite what might seem like (to you) unrealistically high offers. That 14" champagne sparkle floor tom will command some very serious offers by itself. A big component of the collectability of a set relies on the original, matched pieces staying together.
3. If you are compelled to sell the set due to financial need, do not let someone, including your local drum shop, take advantage of your situation. Post more photos of each drum (and the date stamps inside) and our Ludwig experts will estimate a fair market asking price for the set.
4. Even if you don't play, set up the drums, sit behind them, and imagine the joy your dad had playing these before you were born. It's no different than sitting behind the wheel of the car he drove, or going fishing with his favorite rod and reel. There's no price we can put on connecting with our dads.
Don't be stranger. Keep checking in here.
