Beckett Authentication Events

We pride ourselves on carrying nothing but 100% certified authentic memorabilia. We have 3rd party authentication services at our store for open authentication approximately every 2-3 months.  We will post on here as soon as we have a date for them to appear in our store.



Beckett Authentication Date: TO BE ANNOUNCED (last event was 10/19/23).




We are accepting submissions for this event. As always, items can be dropped off at our retail store or shipped to us. Beckett will only be authenticating autographs and will not encapsulate items or do card grading.


If you have any items you would like to have authenticated, we appreciate it if you could have your item at our store at least a day in advance of when Beckett Authentication will be on site. You may drop your item off or ship your item to us any time leading up to the day that they will be here.


Mail-In Items:

You may send your items to our store for Beckett to look at. If you mail your items to us, you will have to pay for shipping to our store and shipping back to you. In your package, please include your name, your phone number, and a return label in the package. We will contact you for return postage if the return label is missing.


Please send your mail-in items to:


Mill Creek Sports ATT: BAS Mail Orders

13616 Bothell Everett HWY

Mill Creek, WA 98012


You can pick up your items a couple of days after they are here.


As always, we have the best interest of our customers in mind and want to ensure your collectibles are authenticated properly to ensure long-term value.


This service is only for authenticating autographs. Beckett does not do card grading and does not encapsulate items through this service. If submitting at our retail store, you must pay for this service BEFORE submitting your item to Beckett. For send-in submissions, we will contact you for payment when we receive your item(s). Items that fail Beckett authentication will NOT be refunded.
