Best advice I've seen is to avoid proof coins until you know what you're doing.  You can make a lot on them as collectibles but it's also possible to lose a lot.  I'm just in startup mode and I've got no short-term plans to buy any proof coins, especially high-end gold ones.  My Brilliant Uncirculated 2p worth - stick to sovs and maybe 1oz bullion until you've got reason to believe you know why something else is a good investment.
That's not to say that collectibles aren't worth investing in, but you're rather jumping in the deep end with that one.

Sovs are a little counter-intuitive but it took me less than a month of hanging about TSF to figure that out.  They've got much lower spreads than other 1/4oz gold and if you trade them here, the going rate is about spot+£10-15, buy or sell.  Given their liquidity here (and presumably on the secondary market in general), sovs are pretty much a no-brainer.

Underrated advice 👏 

The spread on sovs tends to be rather smaller than other 1/4oz coins - maybe 5-7% from a dealer or less if you buy lots.  However, if you get them here the spread is pretty much nonexistent.  Unless they are a key date they tend to go for about spot + £10-20 here and they're very liquid.  Just in the last few weeks I've seen folks rock up with as many as 50 or 100 sovs and flog them all within a few days.
I started down the silver route, but I'm dialling silver back to the odd collectibles that might appreciate in value.  I'm not sure if I'll be buying much if any bullion silver in the future, although I might get the odd tube of Brits or some such if they come up at right confluence of price and spare cash.  I do think I might collect a bit of stuff for the birth dates of the spawn, but this will be a bit of a sideline.
My basic stacking approach is to get at least one sovereign per month, plus whatever is going at the right price - maybe some 1oz or other coins, again if available at the right price. I've got in mind a figure of 100g/year or thereabouts, and I expect sovs will be doing the heavy lifting.  I think the way to do it here is to buy the odd cheeky sov or two if some come up for sale, and get stuff from dealers at the end of the month or quarter if you've not blown it on shiny stuff here.
On the Indonesian side, P.T. Antam bars are pretty much where it's at, so we will be accumulating some gold there as well.  However, this gets you rogered for 11% VAT there (although this may change) so it's not such good value.

And the last of the Q3 silver has arrived.  I also got a 1kg copper bar for ***** and giggles.  According to the vendor it's .99999 fine; not sure whether to take that with a grain of salt. Now, the emphasis in silver is off straight bullion and onto collectibles and semi-collectibles such as the dollaridoos.  I may pick up the odd tube of Brits if it happens along at the confluence of price and available cash.
It's starting to look like a stack now.  Q4 is mostly gold, as is 2023

This is what I'm currently using, same idea as the sovs. Purchased on here and think they have to be imported from America.

Have you been to the Step?
 

Yeah that's the one.

That's one of the 46mm ones, isn't it?
Yes.  I may have even shitposted there.

Oh, no.  I appreciate quality shitposting.

@James32 keeps them in his pockets, and loses them down the back of the sofa! He uses them to put in the trolley at Waitrose.

I knew there was another word for sofa, just didn't have it in my modest vocabulary  

Oh, no.  I appreciate quality shitposting.

The Merkins make the wierdest coins - I've seen Donald Trump rounds for sale, so that sets the bar pretty low.  This doesn't really come as a surprise.

"The Wombles of Wimbledon Common are we" has some strong Yoda vibes to it to be fair.

Silver = speculation
Gold = insurance
They should both have their respective place in a diversified portfolio.

Since I'm about 8 billionth in line to the throne, I figured I'd go for the reverse side.

Coin will be too large to store due to the ear factor! And no one can afford 1kg sov
