Whether you're selling silver coins, jewelry, or bars, it's critical to find a good buyer. There are a ton of businesses that trade in silver, and they're definitely not all created equally.
Frequently the value of a silver item is at least partially subjective, with things like rarity, craftsmanship, and other factors heavily influencing the value. It's important to go into any potential selling situation well informed to help you get the best price!
Whether you decide to go with a national service where your items are mailed in and appraised, or a dealer local to Berne, research is key. Know who you're dealing with by checking with organizaions like the BBB, and know the value of your items by checking spot prices and getting competing offers.
Selling silver can be intimidating at first for a new-comer, but it doesn't have to be! As with all things in life, preperation is the key to success.
As a general rule, you should look at buying legal tender silver coins wherever possible. This will almost certainly include less overhead and premium than other formats, and be closer to the true spot price of silver.
Purchasing rare silver coins should be avoided unless you really know what you're doing. Some subjective measures of value are easy to misjudge, and may result in you getting taken advantage of.
Governments around the world have seized noble metals from time to time, so keeping your entire stash locally could be a bad idea depending on where you live.
Safe jurisdictions like Switzerland should be considered when you get to the point of holding a significant (tens of thousands of dollars worth generally) amount.
If you're not buying an huge amount of silver, you should aim to maintain direct control over it at your home or other property.
If you're investing heavily, to the point where you need a safe alternative location to store it, be sure to go somewhere like Switzerland with strong property rights. It's key to make sure they can't lend or hedge using your stash.
Silver owned through a commodities exchange, or "on paper" is no substitute for physical bars, coins, or jewelry. Exchanges are heavily leveraged, which means if everyone tried to "cash out" at once, there isn't enough physical metal to go around.
Moreover, precious metals are typically meant as a hedge against the complete collapse of the traditional banking infrastructure. If you wind up needing it, you'll want to have it close at hand!
