Fields marked with an asterisk [*] are compulsory.

Sale details

URL of the page describing the lot*

  • The link should point to a specific lot (not to multiple lots).
  • Preferably, the link should point to the lot in the auction house archive. Alternatively, links to bidding websites, such as Sixbids or Numisbids are also allowed.
  • If the lot was sold, the sale price should preferably be freely visible on the linked page without requiring registration. 

Auction house *

Select the auction house from the drop-down list. Only auction houses that have given permission to Numista are available in the list.

Auction *

Select the auction from the drop-down list. If the auction is missing, request it on the forum.

Auction date *

  • Verify that the auction date is correct and change it if necessary.
  • For auctions that span multiple days, pick the day when the specific lot was auctioned.

Lot number

Specify the lot number.

Lot pictures *

  • Upload up to five photos.
  • Use the photographs from the auction house catalogue. 

Sold status

  • Tick the box “The lot was unsold.” if there were no bids, the reserve was not met, or the lot was withdrawn before the auction.
  • Tick the box “The lot contains several items.” if there were several items in the lot. Do not divide the sale price to the number of pieces in the lot, even if all pieces are of the same type, variety, and grade.

Sold currency *

Verify that the auction currency is correct and change it if necessary.

Sold price *

  • Specify the sale price as it appears on the linked page. This is usually the hammer price and does not include auction fees. 
  • If the sale price as it appears on the linked page includes the auction fees, tick the box “The price includes buyer's premium.” Do not attempt to calculate and include the auction fees if they are not readily included on the linked page.

Identification

Version *

Pick the date or variety from the drop-down list. When registering an error coin, do not attach them to any specific yearline, as it would mix up the prices.

Grade

  • Select the grade as specified in the lot description.
  • If the description does not include a grade, do not attempt to grade the item yourself.
  • For items with different grades for the obverse and reverse, select the lower grade.
  • For in-between grades, select the highest whole grade below the in-between grade:
    •  VF-XF → VF
    •  about XF → VF
    •  almost XF → VF
    •  nearly XF → VF
    •  VF+ → VF
    •  XF– → VF
  • Proof coins in mint state should be recorded as UNC.

      • NGC AU58 Details
      • NGC AU Strike 4/5, Surface 3/5
      • ANACS PF64 RB
      • PCGS SP66 BN
