Nice addition to go with my enameled Freedom girl. Rare in the proof version. 

I know it's not much, but thanks to these little beauties, my first ever gold stack now stands at a mighty 0.47ozt and I couldn't be more thrilled. Here's to bringing many more of their siblings into our shiny little family in the future.
 

 

Stunning set of coins recceived today. Shame about the quality. 😭 
Missing frosting around Rims and dings on the QA, missing frosting and black bits on rim of Portrait but portrait herself looks stunning though. 
Still looks stunning as a set.
In 2 minds to keep or try for exchange. 

Worth working out the cost and ease of selling. A few gold sovereigns are very easy to sell as well as being VAT and CG exempt on purchase. Potentially there could be quite a lot of effort and expense selling numerous 1oz silver coins to the same value. If the silver 1oz coins are bought new with VAT included it can reduce the potential profit even if silver has risen at the Spot price.

Wow what a glorious pic!
 

Sovs tend to be extremely liquid, easy to sell here and on ebay and by a dealer

Thanks for your helpful comment!

The above comments are spot on. My thoughts are....
Quite a lot of people enjoy collecting sets i.e. going backwards and collecting coins issued in the past as well as buying coins as they are issued.  The QB's series is a good example.   The joy is often getting assembling a set with hard to obtain older issues Large sets are (clearly) more expensive than buying individual coins, and a lot of people don't have the money to buy(for example) a complete set of 1oz gold QB's in one hit There are exceptions to the rule where someone has assembled a set of particularly rare coins (as far as I have seen) that to sell for a premium but these seem to be genuinely rare coins / sets of coins that perhaps could not be assembled again Best

Beautiful Coins and Quality pics!
 

With anything it depends what you are collecting, when you sell if you decide to sell etc. 
If you're collecting a silver set over the long term its possible they'll just milk and be worth spot. Or like with the Queens beasts you'll get a pretty premium on early coins before the set concludes, and the mint milk it!
The RM lunar series was a mess in my opinion. Pandas, Kooks, Koalas etc were really collectable, but now i think they're run of the mill, High mintage bullion. You might get a premium for a date run or proof set. 
This contrasts with collecting RM historic to modern sovereigns and crowns etc. which has been a real joy but more of a long term, premium collection rather than low premium stack of metal. I think it's a brilliant investment while others look at the premium over spot and tend to avoid for investment - that's never made sense to me personally! 
Either way, I think collecting sets is a sensible way to manifest the metal buying addiction. Or as a hardcore metal investor just buy a monster box, or high quanitity of the same coin for good prices in my opinion, or digital metals. 

Wow what a set, I have a soft spot for coins by the perth mint :)

Really amazing details on every single coin. Like how the kangaroo's head is reflected in the water, the ants on the echidna coin, the structure of the moon... Every single coin is well thought out.
 
The coins are coming from Downies / Australia, minted by the Perth Mint. I like every single coin, the Kangaroo is my favorite so far. 

Thanks for your advice, I've found it very informative

Thanks for the explanation, It definitely helps

Some good collections are special year design sovereigns for example 1989, 2012, 2017. You could go down the route grading these. Collecting earlier modern sovereigns is enjoyable - for example first year/any year for each monarch as examples. 
Crowns are now £5 coins which I tend to steer clear of, but earlier crowns are very collectable, fun, easy to buy in bulk and flip. Also no VAT on them. 
Queens Beasts were fantastic, I think the Tudor Beats will do well too, but VAT on bullion silver kills that collection for me. I think gold will do well for early coins. I think alot of UK ailver collectors will switch into fractional gold, so might be worth looking at.
Hope that helps. 
 

Others will be in a better position to give advice regarding the proofs.  I don't collect them, and I would say that your resale market is much more limited.  Plus they are a lot more expensive to buy in the first place.
That said, anyone who bought and then sold some of the recent gold and silver proofs in the Great Engravers series is likely to have done very well indeed.  The challenge is getting hold of them on release...

I prefer gold to silver, but the same amount of money buys a lot more silver...
As a non-facetious answer, "it depends".  I love some of the 10 oz silver coins and bars, because they are visually very spectacular.  The 1 and 2 oz silver coins are also spectacular, but I haven't been collecting the as a series unless you count the Oriental Border Britannias of 2018-2020. 
There are no bad decisions here, except for the damage to your bank balance in the short term!

I agree with the advice already given.  Collect the set if you seek pleasure of ownership, but be prepared to sell them as individual items rather than the set as a whole, if you want to maximise your return on investment.  Otherwise, just buy individual items that you think will be popular.
The sensible/pragmatic approach in my opinion would be to buy more of the early coins in a series as an each-way bet on the series becoming popular later on.  This, with hindsight, was the best approach to take on the Queen's Beasts coins - the Lion, Griffin and Dragon and to a lesser extent the Unicorn are holding up best.  They were the first four coins.
So in my opinion it would be worth buying several Tudor Beast Lions if you want to go down this route.  There are 3 advantages (it's the first coin, it's a Lion, and it will hold 'England' appeal) and no downsides compared to buying a different bullion coin (the 1 oz gold bullion price is extremely similar to other bullion coins).
If I was 'investing' in Tudor Beasts I'd also go big on the Dragon.
