I'm just going to say that I had no idea that "Cardboard Gold" even still existed. I wonder if that is the same manufacturer I hated back in the 1990's or some new company that took over the name recently. As for the actual topic, I have many thousands of penny sleeves available. I don't know if I have 10,000 of them though. I just know that I have way more than I need or can use unless I started sleeving every PC card. I'm not going to do that though since they are all in pages. Only the vintage or die-cut cards get a sleeve before they go in a page.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
