advanced search

1) I cannot get UK 1 Farthing with value=1
2) what number should I input for denomination like ⅓?
3) https://en.numista.com/catalogue/pieces778.html in this case I think 1957 should be included in searching

1+2 : value is in relation to the currency in this case the pound so it would be 1/960 SEARCH
but it doesn't seem t work in advanced search
3 : you already get the page in such SEARCH

The result of the search by value really depends on what was entered as a value for each coin. For instance, searching for face value: 1 returns this farthing because it has a value labelled as "1 Farthing" but not this other farthing, which has a face value labelled as "1/4 Penny = 1/48 Shilling".

Alternative ways to search for farthings is to search face value: farthing (this will also return fractions of farthings) or face value: 0.00104166. Perhaps this could be improved to allow searching for "1/960" instead of "0.00104166".

Coins of ⅓ farthings can be searched with face value: 1/3 farthing or face value: 0.00034722.

thanks to all for the replies

• I thought the "value" field only works with numbers. I input "1" and it doesn't work for 1 Farthing. maybe "1 farthing" works.
  
• for the Spanish 1957 coin, it is OK with "year" field, but doesn't work with "Gregorian year" field
