Such non-circulating coins are often just worth the Silver price, nothing more. It is true that many try to inflate the price (including the mint / company that produces them in the first place), but the interest in them, often totally obvious by the mintage numbers, means that there is a very limited market for such coins.
They will often sit around in shops and online for inflated prices not selling, until eventually they sell for the bullion price or are melted for the metal.
You bought the coin, so you know exactly how much you paid for it, unfortunately the silver price is high now and to be honest in a few years I suspect it will be lower and the cost of your purchase will never be recovered.
The lack of interest in these coins is often cemented by most collectors purchasing one (on the hype of being proof, low mintage, etc) then realising they have been slightly conned into the purchase and never purchasing such coins again. Very few collectors continue to purchase these types of coins, those that do mostly do it on the speculative bullion market, and then there are the very few who collect these types of coins for the numismatic experience, often as a side or supplement to other types of coins in their collection.
The biggest and most sought after bullion coins are the US and Chinese ones, these are also the most beautiful ones in my opinion, eagles pandas etc, which push their value up - but small country bullion or historical figures on these coins are not comparable in price, because you are narrowing the interest further in an already niese market.
Libertads are my favourite. From what I have seen, those, and other Mexican bullion, carry the highest premiums. At least in my country.
Apart from Chinese pandas, of course. But those are not really bullion anymore, rather semi-collectible coins.
I also like the Canadian ones, specially those large sterling issues for the Olympics. Those are usually available for melt value. (Which is why I like them, although I suppose they are technically not bullion)
For some reason, I never was a fan of American coins and bullion
