Sell a collection
Thinking about selling an estate or collection?
Start by telling Kevin what you have and what you need to accomplish. A jewelry collection, boxes of vintage toys, or an estate with several kinds of property can raise different questions — what should be sold together, what to gather, and whether an auction is a fit.
Start with a short description and the location of the items.
Questions worth asking on the first call
- What kinds of property may be accepted?
- Which auction format suits this collection?
- Who handles each task from listing to collection?
- What are the seller costs and the payment arrangements?

Before bidding
Read the lot details and plan pickup or shipping
The catalog is the place to check each auction's terms.
1. Choose a catalog
Review the item description and photographs, then follow its instructions to register and bid.
2. Work out the full cost
Check the buyer's premium and any applicable taxes listed in that catalog before you place a bid.
3. Plan collection or delivery
Read the pickup or shipping arrangements. Where shipping is offered, confirm eligibility and packing and delivery costs first.
4. Confirm the close
Check the closing time and time zone so you know exactly when the auction ends.
Terms are set auction by auction. Do not treat one past sale's premium, pickup window, or tax status as a standing rule — ask Kevin about anything that is unclear.

How do I ask about selling a collection?
Call Kevin at 660-287-1410 or email sprint20k@yahoo.com. Describe the property, its location, and your timing so you can discuss whether it is a fit.
What types of items have appeared in the catalogs?
Past examples include estate jewelry, vintage toys, advertising pieces, games, and military collectibles. Contact Kevin to discuss a particular item or collection.
Is there a buyer's premium?
Buyer's premiums can vary by auction. Check the percentage listed in your catalog and include it when calculating your costs before bidding.
Can I have items shipped?
Check the auction and item instructions before bidding. Some past auctions offered packing and shipping through a local UPS Store, with those charges separate from the purchase. Confirm eligibility and costs for your items.
Where and when do I pick up purchases?
Use the pickup instructions for the auction you entered. Confirm the appointment, address, and collection window; the business contact address may not be the pickup location.
