Depends on where you sell it. If I take my Silver American Eagle to a precious metal shop they would probably give me less than spot.
You can take a look at the PCGS guide for a general idea (of graded examples) although some will be high and others low. At least it will tell you which ones are relatively more expensive. https://www.pcgs.com/prices/detail/silver-eagles/939/most-active I believe these are also in the greysheet, but that requires a paid subscription. I would recommend to look these up on eBay to see what auctions bring. That will be the best idea of online prices (they might be less in person since there are no eBay fees or shipping-although some coin stores will charge even more than eBay).
All depends upon how much of a hurry you are in. For instance on ProvidentMetals, their current BuyBack for any date is $27.14. You can peruse all their dates to get an idea. but a 1986 BU is $39.14 Apmex buys back. You Local Coin Store buys back, Coin Shows, but you'll get the most selling to other collectors of course you have to find them. But if you went through Provident, you can get an idea of each year BU buyback price.
Does the Red Book list the value of Uncirculated? Is it the bullion that they don't list? In my copy they only generalize the values.
The Red Book I have lists Uncirculated and proofs. That should be good enough for any insurance company, even if the prices are on the high side. It can be found under Silver Bullion in the 2022 copy.
Thanks CN. I have the 2019 Edition. It only values them in general. For my 75th Anniversary I might get myself a new issue of the Red Book.
I believe legally their intrinsic value is melt, but a coins real value must be determined by the Buyer/Seller My experience has been a stall until brief statute of limitations elapse, and then an average of what local BM dealers may pay on a specific date. JMHO
The value of YOUR COINS is what you paid for the coins! Any value other than that, in the event of an insurance report, should legally necessitate a Capital gains/loss filing, based on your recovery amount. Any other fictitious amount, as selecting an amount from a publication that's more than likely outdated upon publication, would be difficult to justify in a hearing where purchase proof is required. You can supply any amount you desire, which would be equivalent to selecting a fictitious value that generally changes instantaneously with time. JMHO
You're making an assumption the OP is filing an insurance claim. That may be the case, but it is certainly a possibility the value is needed for establishing a premium in a new policy. So if you bought your home in 1957 for $18,000 and you're still living in that home today you're saying the value is still $18,000 for insurance purposes, even though the FMV is now $425,000? Purchase price and value can be wildly different dollar amounts. Purchase price is a stationary target. Value can fluctuate with time, market, condition and desirability. I beg to differ on your interpretation of value on YOUR COINS as well. Once again, you're assuming the need for value is for an insurance claim. Capital gains or losses are only established when there's a sale, transfer or loss of said asset. If the asset is still in their possession there is no capital gain to report. As you stated, "...value that generally changes instantaneously with time.", could also mean the Red Book value was correct at some point in time. Establishing value for insurance premium purposes typically means you declare a reasonable value for your asset and the insurance company attaches a premium based on your declaration of value. There is no one exact value in a situation like that.
Wait a little bit and can probably get the current edition at a discount as the next version will be out. My LCS does this every year.
