Investment and speculation

Hello knowledgable people
I'll like to ask what people think about coins as a future investment. Silver and gold. I know they are two very different investments, so mostly gold though. I have thought of buying gold as an security, for far into the future. The question being something like the following:

What do you think is a fair premium? 10% maybe? I prefer coins intended for circulation, so they're useally old.
Do you think gold is a good investment or should I stick to silver?
Is it a good way to combine hobby and security? It's nice to have just as a curiousity though.
What's the expected future of gold and silver? Predicted to go up in value?
Other things to be knowing about?
Is one better to buy than the other?
Or is it just better to buy it, as a numismatic piece for "cheap" and if it gets up in value, it's just nice?

I know silver is the most affordable, and gold hold the most value to size ratio.

Hope to get some inputs from you, since I'm still learning about precius metals in general
Thanks and happy holiday, whatever that may be

I dabble in bullion, but not seriously. Everything I have is also a coin of sorts (Chinese Silver Pandas, Chinese Gold Pandas, US Silver Eagles).
I scoop up any silver circulated coin I can find as well.
For my bullion coins, I'm only buying graded. Not so much for the grade, but because there are so many fakes out there. It's just a way for me to be more certain that the coin is legitimate. It should help with resale down the line as well.

I feel like coins (vs bars and nuggets) are a good investment since you are doubling your potential buyer base. Some will buy just for the metal, some will buy for the coin.

And if it's a scarce coin, it tends to be valued significantly higher than just the melt value.
That said, it will cost you more up front to purchase a precious metal coin. So the question is, how long will the melt price take to catch up to your purchase price?

My intention with my collection is to hold onto it until well into retirement. In another 30-40 years I'd like to think I'll get a pretty good return on my investment.

@Jamtrup if you're asking about investing in bullion than I believe @glorkar has provided a fairly decent answer: look into buying Precious Metals (PM) in terms of long term investments (& regard it as 'bullion' - not in terms of collectible coins).

It is a subject/question asked many times in many forums across the net. Here's when it was discussed on Numista fairly recently.

When you ask about coin collecting as a hobby (& whether one is "investing or speculating" on any particular coin) then this is an entirely different question & I'm sure that you'll get many varied responses. Most collectors don't speculate. It can also elicit emotional replies because many collectors don't see their hobby simply as an investment (ie: a coin is always a bit pricey because that is what he/she wishes to add to his/her collection). Coin collectors, I believe, collect coins for the pure enjoyment & satisfaction of adding a particular piece. If a certain coin goes up in value over time, great, but that wasn't why it was bought in the first place. Collectors are in it for the long haul.

Investment & speculation on coin BV (Book Values) has been a new trend brought on by Youtube videos, IG and other social media platforms that sensationalize plucking a fortune out of common change. The producers of these videos will make outlandish claims to drive up # of "LIKES" & tend to speculate with little research (& forget proof). Doing this is a disservice to the hobby b/c they don't really look into why a particular item is desired (or even worse- they'll declare we're headed into a "cashless society"), etc, only to jack up their audience.

As an American, I consider gold and silver a necessary part of financial protection against inflation.
The FED has authorized so much printing that 40% of all bills in circulation were printed in 2021.
We are following the Weimar republic.
