Frequently asked questions
Where can I find authenticated investment grade luxury pieces for sale?
You can buy authenticated investment grade luxury pieces directly from CLB XXIII, either online or in person at the Cincinnati or Beavercreek stores. Every piece is inspected before listing as part of CLB XXIII's authentication process. Because most items are a single unit in a single size, the product page is the best source for availability.
How does CLB XXIII authenticate investment grade luxury pieces?
CLB XXIII authenticates investment grade luxury pieces through a multi point inspection covering material and construction review, brand identifier verification of tags, logos, engravings, fonts and serial or date codes, and a product specific evaluation against known authentic examples. An automated check runs first, then trained specialists review each piece by hand.
What does investment grade mean at CLB XXIII?
Investment grade luxury pieces at CLB XXIII are pieces judged especially scarce or well preserved during authentication, based on condition and how closely they match known authentic examples. High value categories go through enhanced verification. Since these are typically single unit listings, the live product page is the best source for current status.
Why can't I choose a size for investment grade luxury pieces?
Investment grade luxury pieces at CLB XXIII typically appear as a single unit rather than in multiple sizes because each piece is sourced and authenticated individually. That is why size options are limited on most listings, and why the live product page reflects real time availability rather than stock across sizes.
Can I see investment grade luxury pieces in person before buying?
Yes. CLB XXIII has physical stores in Cincinnati and Beavercreek, Ohio, where you can see investment grade luxury pieces in person. Because most pieces are one of one, in store availability will not always match what is listed online, so it helps to check with the store or the live product page first.
How do you authenticate every piece?
Every item is inspected in-house before it is listed. We check box labels, stitching, hardware, material quality and construction against known factory details, and each piece carries our lifetime authenticity guarantee.
Are there any buyer fees?
No. The price you see is the price you pay. We do not add buyer premiums or platform fees at checkout.
Can I place a deposit and pay the balance later?
Yes. We take a non-refundable 10% deposit that applies toward the total price of your order. Speak to a private client adviser to set one up.
