A part-time shop run by a Navy veteran out of our basement in Dayton, Ohio — with my kids learning the business along the way. TAG-graded cards only: every grade provable, not just promised.
Our Story
C3-DO is a part-time shop run by a Navy veteran out of our basement in Dayton, Ohio, with help from my kids who are learning the business along the way.
I started selling on eBay and still run things the same way: honest photos, direct communication, and no empty promises. Shipping supplies were chosen through trial and error until they met the standard I wanted.
This store focuses exclusively on TAG-graded cards. The transparency is the point — every card comes with a full DIG report so you can see exactly why it received the grade it did. On Shopify, where there are no eBay buyer protections, that kind of verification is non-negotiable for me.
The catalog stays selective on purpose. Mostly baseball prospects, the cards I've collected longest. Sold cards remain visible so you can see what's moved.
Packed and shipped from Dayton, usually within one business day.
You can verify my selling history on eBay under c3dohub.
Trust
Every graded card links to its public cert and full DIG report. You can verify the grade — and see exactly why it earned it — before you buy.
Service
The same person answers the email, packs the order, and stands behind the sale. Communication is direct, and most orders ship the next business day.
Quality
Shipping materials were tested and refined until they met the standard. The catalog stays selective, focused mainly on baseball prospects, with sold cards left visible for reference.
