There are many parameters that determine the value of a silver coin
RAM $5 seem to be the ones to avoid- having said that I'm sure many have made money early on with these coins but due to limitations of purchase amounts that profit will be short lived
Perth Mint opals seem to be the diamond in the rough - they take a while to take off but once they do they retain their value especially the lunar series
I think it is a bit late to get into 2016 Lunar Opal Monkey coin as it started to spike in 2020
Maybe Lunar 2023 + 2024 still have some potential to go up but no definite trend as yet though 2023 almost double its issue price at the moment and 2024 at over 60%
Since lunar opals make up 4 out of 10 of the top 10 they maybe a way to be longterm
Don't disregard
Perth Mint swan coloured coins also
Just my opinion
