What's the most reliable and accurate. A few of them actually have different numbers as I'm switching between the sites in real time
Kitco is the least up-to-date, especially when they display the Kitco Silver Fix, which is a snapshot from a specific time of day, and doesn't get updated for 24 hours.
I did some research on this and I'm stuck. Different sources are giving different prices for silver at the same second in time. I haven't been able to figure out what's going on. SilverPrice.org seems okay. It's especially frustrating when different dealers quote different spot prices at the same instant in time. I've noticed that dealer spot prices tend to be a bit higher than non-dealer sources, which might be intentional and corrupt since it makes their premiums look smaller... APMEX quotes the highest silver price of all sources.
They have plenty of other measures of spot, if they were not up to date dealers would not pull web data from them for pricing.
I Like goldprice.org But One I use the most is https://www.goldbroker.com/charts/silver-price/aud as They have a great graph including the historical graph
Other measures? You mean like some kind of live feed? I've seen that but it wasn't clear where the data was coming from. I assume COMEX since Kitco doesn't operate their own exchange, but i wasn't able to find out what their silver price was based on. It bothers me that there are all these different silver prices at the same instant in time.
Also consider the London Bullion Market Association (LBMA) Gold - The price is set twice daily (at 10:30 and 15:00 London BST) in US dollars. Silver - The price is set daily at 12:00 (London BST time) in US dollars. Sometimes, it's good to know the timings / very important to know when the metal prices are set. http://www.lbma.org.uk/home Here's a time converter https://savvytime.com/converter/australia-melbourne
