- Many timed auctions use a soft close, where a late bid extends the clock. Check the lot page; where it applies, a last-second bid just restarts the clock.
- Enter your walk-away as a max bid. Proxibid then bids for you one increment at a time, only as far as it has to, and never past your number.
- Decide the number now, not in the final minute. Lots that end above value usually do so in a bidding war.
The walk-away bid is arithmetic on the melt estimate above and your own inputs. It is not an appraisal, and it is no promise the lot is worth that to anyone else.
What the comp rests on
- Source
- Metal content at today's spot price. A floor, not a market price
- Grade assumption
- None. The listing does not state a certified straight grade.
- Metal read from the title
- 1 oz gold. Taken at the auctioneer's word. If the lot holds less than the title says, this floor is wrong.
- Measured against
- The current bid of $4,500.
- Confidence
- Moderate. Parse 60%, comp 85%.

What is uncertain
- Coinsel has not handled this coin. Everything above is read from the auctioneer's own title, description and photos.
- Auction totals are not the hammer price. Buyer's premium, sales tax and shipping are on top, and they commonly add 20 to 30 percent.
