Hi.. I'm glad you posted this topic. The ride cymbals are always worth considerably more than the smaller cymbals, except for the hihats. If you've got a pair of 14" K's they're worth more than the 16" crash.
The range on eBay for 22" K Istanbul is between $900 and $2200. BUT that isn't relevant to you because your cymbals are smaller.
The range for a PAIR of 14" hihats K Istanbul is between $450 and $800.
The range (these are eBay ranges) for the other cymbals are what Bill says.
If you are looking to get values for your drums and cymbals then I think the drums and cymbals are going to be worth around $1000, depending on the value of the Ajax drums and Premier Floor tom. Why? You're wanting to sell them and buy a set of electronic drums. Unless you're an adept eBay seller who can split them up appropriately and sell them, figure the low ends of all the values.
Obviously value is what someone is willing to pay you for them.
These all assume excellent condition with no cracks, or problems.
People telling you to keep the cymbals assume you may find out later how rare they are, and decide you want to play jazz with them. THAT may never happen. I would be careful about trying to buy a new electronic kit that will lose its value by 50% as soon as you buy it, with funds paid for by selling off a vintage set that has its value stabilized.
The main reservation you should have in selling these is if they're a family heirloom. If there is sentimental value or something, you should get a job and pay out a set of electronic drums and wait until you're financially stable enough to really figure out what these vintage items are worth to you, because you may decide to keep them and really get a good value from them by playing them, or you may decide to sell them, keep in mind that time is on the buyer's side. A fast sale translates into less money for you, a slow sale, taking time to research, find suitable buyers, etc. will translate to better money for you (usually), the seller.
Good luck! Have fun.
