Grade-to-Bid
A grade is an opinion.
The market prices it as a fact.
One grader, one afternoon, one number — sealed in plastic and treated as settled forever after. Grade-to-Bid asks a room of experts what they would actually pay, without letting them see what the label says.
What the bidder sees
The coin, not the verdict.
A bidder gets the coin at full resolution — surfaces, strike, toning, every mark. What they do not get is the grading company's answer. They have to arrive at their own, and put money behind it.
The crop is prepared and confirmed by the seller before a session opens, never by a machine alone. A bad crop would leak the label and quietly ruin the session.
So everyone's bidding on a coin nobody can identify?
The mechanism
Four rules, and what each one is defending.
Sealed
No bidder sees another bid. No seller sees any bid. Not until the reveal.
A visible bid is a floor to hide behind. The point is an independent number, not a reaction to someone else’s.
Bonded
Submitting a bid holds SLVR equal to the full bid amount, debited at that moment.
An unbonded bid is an opinion with no cost. The bond is what makes the number mean something.
Revealed together
Every bid surfaces at the same instant, or none does. Fewer bids than the seller asked for and nothing is revealed at all.
A staggered reveal lets a late bidder price against an early one. A coin with two bids must not be shown as though it had eight.
The seller decides
The seller has 48 hours to take one bid or none. No obligation to sell.
The seller is buying information first and liquidity second. A window that never closed would be worth far more than the free look this is meant to be.
A bond is never forfeited. If the seller takes another bid, declines them all, or lets the window lapse, it is released in full. If your bid is the one taken, it pays for the coin.
What comes back
Not a price. A distribution.
Illustration — the pilot's first sessions are still running.
One number tells a seller what somebody would pay. Six numbers tell them something the market has never shown them: how much the experts disagree, and in which direction. A tight cluster means the holder's grade is doing its job. A wide one means the plastic is carrying weight the coin itself will not.
Every bid arrives with money already behind it, so the distribution is not a survey. It is what a room of people were each willing to commit before they knew what anyone else thought.
Who bids
Invite-only, on purpose.
To bid
Bidding is limited to an invited pool of dealers and graders. A bidder needs an active account, a shipping address on file, and enough SLVR to bond the number they intend to name.
The restriction is the point. Competing expert capital is what makes a spread worth reading; a pool anyone could join would produce a spread that means nothing.
To sell
Any member with a listed coin can open a session and ask the pool for a number. No invitation needed, and no obligation to accept whatever comes back.
You keep the coin unless you decide otherwise. Declining costs nothing.
Open a session →Grade-to-Bid is an invite-only pilot, and it is new.
Grade-to-Bid adapts the Grade-to-Own protocol proposed by Daniel H. Oostra in CoinChain, with the option reversed so it runs to the seller rather than the grader.
