Denomination is an essential caracteristic of any numismatic description of coin (Q41207) or coin type (Q113813711). We already have face value (P3934) to express the value of currency, but it can't be apply for a lot of coins for example in Antiquity where the value of the coin or type of coin is never inscribed and the the value of metal in the coin is the denomination. At the moment, people are mostly using subclass of (P279) and a bit instance of (P31) to express the value of ancient coins, but it would be better if we have a specific property for this.

Furthermore, it would also be possible to map this property to Nomisma, a leading platform in numismatic, which already have this kind of property in their ontology. Liber008 (talk) 16:12, 16 August 2024 (UTC)[reply]

Discussion

Shouldn't this be in "instance of", like I did here? A single coin is definitely not a "coin type", right? --Tolanor (talk) 17:11, 16 August 2024 (UTC)[reply]

@Tolanor Actually, this item is a type of coin (RRC 415) and should be model as such. The Nomisma infrastructure seems to have some issues today, but when it will be working, you can see here that it represent a type of coin in Crawford's work: Roman Republican Coinage. For example there is some of them for sale here. --Liber008 (talk) 17:43, 16 August 2024 (UTC)[reply]

I see, I didn't dig enough. Then the proposal makes sense. --Tolanor (talk) 18:22, 16 August 2024 (UTC)[reply]

Support Useful property. It also makes querying for particular denominations a bit easier, even when face values can be retrieved. TiagoLubiana (talk) 14:35, 20 August 2024 (UTC)[reply]
Comment I started the creation of this property at denomination (P12949) but Wikidata seems to be having issues right now that are preventing me from being able to add any further statements. I'll return to this later and see if the problem has resolved itself. --Lewis Hulbert (talk) 11:27, 23 August 2024 (UTC)[reply]
Reported here as I'm still having troubles with it. Lewis Hulbert (talk) 15:06, 23 August 2024 (UTC)[reply]
@Lewis Hulbert, It's happened several times with me, and all the times when I added one "Wikidata property example"! I believe now you will be able to complete, as it’s taking 3-8 hours to back in normal. Regards, ZI Jony ^(Talk) 23:38, 23 August 2024 (UTC)[reply]
