It all depends. Some silver coinage is common, beat up, damage, etc. It's worth junk value. Then again, I have a PCGS grade MS-65 Silver Dollar that goes in the $5,000 range. So it all depends on date, mintmark, condition and demand.
Yes, common date worn silver coins are valued concurrent to their silver content. If you want an easy calculator for your silver coins, go to Coinflation.com.
It depends on the condition of each coin. Most coins in better condition have a numismatic value which is often greater than the melt value. As the condition deteriorates during circulation, the silver melt value comes closer and closer to its junk value.
It depends on there condition and rarity with what types and kinds of silver coins are you referring to?
For US coins, it's worthwhile to have a copy of the Red Book. It lists nearly all US coins, with their values in various grades, and a guide to grading each type. The values tend to be inflated -- you can usually buy a coin for less than Red Book value, and you can rarely sell one for anything near Red Book value, especially to a dealer -- but it will give you an idea of relative value, and also show you which dates and types are rarer and more valuable. For non-US coins, I'm not your guy.
Depends on denomination, mintage, rarity. For examole a silver Spanish Reales from the 1700's or 1800's could be worth much more than a Canadian silver quarter from the 1940's.
I have 2 residences. The coins are at the other one. Watching the Rose Bowl here. I can try to get pics up over the weekend.
This is how the Krause guides come in handy like I was posting to on your other query. They state the silver content in silver based coins and then you have to do the math to figure what their value is based on the silver content. Some are 600 fine/825 fine/900 fine/ 999 fine, etc. And like what was said before, condition is everything. A coin worn smooth is only worth it's weight and fineness in silver.
Not necessarily. Depends on the condition and rarity and also the type of silver coin. Silver Eagles are worth more than the junk rate. Worn Mercury dimes are worth about melt, depending on the year. A 1916 D Mercury is worth far more than melt.
As noted, there is numismatic value and the value of silver. In some cases, silver is worth more than the coin. In others, the coin is worth more than the melt price. You need to determine what you have, whether it can be sold/traded for melt (some countries prohibit it), or if it has greater numismatic value. You wouldn't want to sell a $5000 coin for current melt. If that's the case, many here would gladly resolve that matter for you.
