Auctions to Watch This Week: Sirius #418 Closes June 18, Heritage Showcase June 27
A weekly auction and a major showcase are closing in the back half of June. Sirius Sports Cards #418 ends June 18 with 500-plus lots, and Heritage's Sports Showcase wraps June 27. Here is how to use them.
It is a busy stretch on the auction calendar, and a couple of sales are closing this week that are worth watching even if you are only browsing comps. From a fast-moving weekly auction to a major house's showcase event, here is what is on the block in the back half of June.
Closing this week
Sirius Sports Cards Auction #418 wraps up June 18 at 11 PM EST, with more than 500 lots crossing the block. Weekly auctions like this one are a useful pulse check on the mid-market: lots move quickly, results post promptly, and the breadth of material gives a real-time read on where prices are landing right now.
On the horizon
- Heritage Sports Showcase is set to end June 27, the kind of curated event where higher-end and vintage material tends to surface.
- For context on scale, Heritage's mid-May Sports auction realized roughly 23.5 million dollars across more than 4,200 bidders, a reminder of how much money is still flowing through the top of the market.
How to use an auction even if you are not bidding
Closed-auction results are one of the best free tools in the hobby. Watching final hammer prices across grades and parallels helps you build accurate comps before you buy or sell anywhere else. A few habits make it more useful:
- Track the same card across grades to see how much each grade step is actually worth today.
- Note buyer's premiums so the realized price you record reflects what the winner truly paid.
- Watch sell-through, not just top sales — what does not move tells you as much as what does.
Whether you are bidding or just building comps, a week with a weekly auction closing and a showcase on the horizon is a week worth watching.
