Items that are bulky and costly to ship are better to bring in person to one of our events or our office in St. Louis. Examples would be oil and watercolor paintings, toys, and firearms. If you’d like to get an idea of value before making a trip you can always send us a picture with information about the item and we will reply with an estimate.

No.  Appraisals are subjective and done strictly for insurance and replacement value.  You can expect a cash value on your item to be 10%-40% of the total insurance value. The exception to this rule is jewelry with larger stones or older appraisals. Our specialist will walk you through the appraisal.

Yes, we can give you a price range.   Fill out the form on the website and speak with Estate Specialist.

Yes.  A GIA certification or a well-known certification company (for diamonds, fine art,or autographs) can increase its value.

Often customers come to us with expectations closer to what they paid retail for a piece, or a number in mind from an insurance appraisal. The number from an appraisal represents an insurance coverage value for replacement costs if the valuable was lost, stolen, or broken beyond repair. Appraisals are good for indentification purposes, but do not translate to the current value of an item. Our offer ranges take into account current market values and recent sale comps on the open resale market. 


For example, a 1970's gold nugget ring with a .25ct diamond would appraise for $3000.

But who would purchase this item to wear in today's fashion?


The appraisal only takes into account how to recreate this item to be sold in a retail setting. A ring like this is no longer in fashion and would not sell in today's market, but would be recycled for parts at approximately $300 for the gold and diamond value.


All gold is not the same, there are different purities that hold unique characteristics and values:

24k = 100% pure

18k = 75% pure

14k = 58.5% pure

10k = 41% pure

Step 1. Print two copies of your shipping label: inner and outer box labels.

  • If you do not have a printer, contact us and we can mail you a shipping label, which would arrive in 3 to 5 business days.

Step 2. Securley wrap your valuable in bubble wrap or paper and place in a small box or container.

  • You can use any box, pouch or padded envelope that will fit inside a larger box.

Step 3. Put the small box or container and inner label in a box and seal securely with tape (a sturdy, used box will do).

  • You can use any box you have at home that is smaller than 13" x 11" x 3". If you are reusing a box, please make sure it is not torn or damaged, and remove any old shipping labels.
  • Don't have a box and packing materials? Contact us and we will send you a free shipping kit.

Step 4. Seal the outer box and attach the shipping label to the outside.
