About Us
Millennium.nyc started the same way most collections do — buying, trading, grading, and slowly learning what actually matters over time. Condition. Authenticity. How something is handled before it ever ends up in your hands.
This shop is built around that mindset.
We’re collectors ourselves, which means we care about the details that don’t always show up in listings: clean surfaces, sharp corners, proper storage, and realistic descriptions. If something doesn’t meet our own standards, it doesn’t get listed. Simple as that.
Who We Are
Millennium.nyc is a trading name of Sweet Mamie NY LLC, an independently owned online retailer of collectible trading cards, sealed trading card game product, die-cast, figures and collector supplies. We are based in New York and ship every order ourselves — we are not a dropshipper, we do not print or manufacture product to order, and we do not act as a marketplace or agent for third-party sellers.
We are an independent retailer. We are not affiliated with, sponsored by, or endorsed by The Pokémon Company, Wizards of the Coast, Mattel, Funko, or any other rights holder. Product is sourced through authorized distributors, including Pokémon TCG product supplied by an authorized distributor for The Pokémon Company.
What We Carry
Our inventory changes often, but the focus stays the same:
- TCG singles and graded cards (Pokémon, Magic, and more)
- Sealed product and high-demand releases
- Collectibles, figures, die-cast, and limited drops
Everything here is hand-selected and checked before it goes live. No mass uploads, no filler inventory.
How Orders Are Handled
When you place an order with us, it’s packed the same way we’d ship something from our own collection — protected, clean, and secure.
- In-stock orders ship within 1 business day (2:00 PM ET cutoff, Monday–Friday)
- Professional, protective packaging
- Tracked shipping on every order
- Clear communication if anything comes up
We ship within the United States only. Full details — costs, the free-shipping threshold, handling and transit times — are in our Shipping Policy.
Returns
Eligible items may be returned within 14 days of delivery, in the condition in which they were shipped, once a return has been authorized by us. If we make a mistake — wrong item, missing item, listing error, or damage caused by our handling — we will make it right and we pay the return shipping.
Because of how the collectibles market works, some categories are final sale, including sealed and single trading card game product, blind or chase-element items, and pre-orders. Exactly which items are final sale, and how to start a return, is set out in full in our Returns & Refunds Policy. Please read it before ordering.
Why We Do It This Way
Millennium.nyc isn’t about chasing volume. It’s about being a store people come back to because they know what they’re getting: fair listings, solid packaging, and someone on the other side who actually understands the hobby.
If you ever have a question, need clarification, or are looking for something specific, you’ll be talking to a real person — not a ticket system.
