How often are Spot Price's of Precious Metals updated?

They seem a bit off right now, any idea if and when they get updated?

If I remember correctly it's daily but it sometimes happens that Xavier has to force restart the update process.

Hello,
Precious metal prices are updated once a day. I checked the gold price and it seems correct (56 085 EUR/kg). Could you please elaborate about the issue?

Hi Xavier
It is the Platinum Price
It is now $1000 an Ounce
My Ounce shows $971 on the Numista Page https://en.numista.com/catalogue/pieces321197.html

There seems to be some discrepancy in the price of Platinum depending on the source.

Numista uses the rates of https://openexchangerates.org, which gave $971 this morning, and $977 right now.
Oanda also gives $971 today: https://www.oanda.com/currency-converter/en/?from=XPT&to=USD&amount=1
Xe.com shows $973 for this morning and $997 right now: https://www.xe.com/fr/currencyconverter/convert/?Amount=1&From=XPT&To=USD
And Apmex shows $1009 ask price for this morning and $1022 right now: https://www.apmex.com/platinum-price

I'm not very familiar with precious metal pricing. If anyone has more information about how the price of platinum is established and what are the most reliable sources, feel free to share.

Yes, I see what you mean. Ive been watching Platinum for a while and it has BEEN all over the place.
We can close the case, I now see there are a lot of sources.

I was wondering myself how often the bullion values are updated.

  I love Numista and use it as my primary go-to for quickly & easily looking up coins at flea markets & coin shows.

     But I also love the ease in finding bullion values when I'm buying junk foreign silver coins. I knew Numista dosen't update in real time (unfortunately)…, but just wasn't sure if it updates a few times a day, a week or what.

Hello,

Bullion prices are updated once a day.

Following a question here, bullion prices and exchange rates are now updated every hour.
