I don’t have a massive collection like some people out there, but I’d say I have a very good collection. It’s all limited-edition stuff that is worth collecting. I’m primarily interested in coins and porcelain, but I don’t buy things to make money; I’m not a collector in that sense. My reason for doing it is the love of it; I love the Royal family and I love what artists can do with metal and porcelain. That’s what I think about – all the design and the hard work that goes into it. Valuing the royal family’s private jewellery collection is exceptionally difficult. A professional valuation would require each stone of each item to be inspected for occlusions or other imperfections that cannot be detected by the naked eye. Two maces, made of silver gilt over oak and date from between 1660 and 1695, will also feature. These are the ceremonial emblems of authority which are carried before the sovereign at events such as the State Opening of Parliament. AMPULLA These include the Sword of State, which symbolises royal authority and was made in about 1678, and was used at Charles' investiture as Prince of Wales in 1969. Also to feature will be the Sword of Temporal Justice, the Sword of Spiritual Justice and the Sword of Mercy, which were first used in the coronation of Charles I in 1626.

The Sovereign's Orb, another item commissioned for Charles II's coronation, is a globe of gold with a cross mounted on top, surrounded by a band of diamonds, emeralds, rubies, sapphires and pearls with a large amethyst at the summit. It is a representation of Christian sovereignty. CORONATION RING The Coronation ring, known as "The Wedding Ring of England" and composed of a sapphire with a ruby cross set in diamonds, was made for the coronation of King William IV in 1831. Worn at every coronation since then, it symbolises kingly dignity. SWORDS AND MACES There are circumstances that will make the manufacturing of a product worth more too. “Anything with a revised date usually fetches more than an original date. For example when Prince Charles married Camilla Parker Bowles, their wedding date was delayed due to the death of Pope John Paul II,” adds Fox. “Memorabilia was already made by this point, and could not be changed, so anything with the amended date on it will be worth a little more than the original.” However you're celebrating King Charles' coronation, make sure you inject a bit of crafty joy into it with one of these gifts – or give the make to a friend who's particularly excited about our new king. This set has been produced by the Royal Collection. There is nothing more British than a cup and saucer and because of this its value will hold and rise.

There are a lot of factors to consider when determining the value of an item,” says Hannah Webbe, coin specialist at online vintage store Vintage Cash Cow. “These include the condition of the item, its age and its scarcity.” There is a correlation between value and public perception,” says Webbe. “Princess Diana is considered one of the more popular royals, so the market for her collectibles is much larger. In contrast, Prince Andrew is a bit less admired at the moment and that translates to the value of collectibles based around his name.” Among all this there is one forgotten element: taste. “Personal preference is extremely important in collecting,” says Webbe. “Taste is so crucial to what is and what isn’t collectible. If you like something, there’s probably a good chance someone else will like it too. That’s a huge factor that people forget about in the resale market.” This paper weight is made from crystal. As we start to become paperless, manufacturers are starting to produce less paperweights.

With the launch of the Coronation Emblem in February, King Charles and Queen Camilla have opened the floodgates, relaxing the rules on usage of royal photographs and official insignia so as to allow anyone to produce their own Coronation merchandise. The only rules are that it must be in good taste, free from advertising and carry no implication of royal custom and approval.

If you do have royal merch that you’re looking to sell, then now is a good time to do it. Increased visibility for the Royal family during the Coronation will almost certainly spur interest from collectors. Around Queen Elizabeth’s funeral, searches for memorabilia on Google doubled. Similarly, around what would have been Princess Diana’s 60th birthday, merchandise commemorating her saw a rise in value. Even where an estimate can be made, there is then the ‘royal premium’: the association with the royal family, which could multiply the value many times over. Ahead of the Coronation, it might be tempting to go out and acquire as much merchandise as possible, with an eye on selling it in the future. However, it will pay to be judicious. “Mass-produced items like mugs, tea towels and flags are highly unlikely to rise or even retain their value over time, so invest in limited-edition merchandise such as coins and stamps,” says Lo. The Royal Mint has created a 15kg gold coin in celebration of the King Charles' Coronation. It is the largest coin produced by The Royal Mint in its 1,100-year history with only one made featuring this design. The coronation coin range:

CORONATION SPOON

I think I got my interest in the Royal family from my mother. When I was a child she would always read magazines about the Royal family to me. Her favourite was Princess Margaret; she’d tell me about her exploits, about Peter Townsend and everything. I always wanted to hear about them.

There are kits to make street party decorations for beginner crafters, ideas of projects to work on while you're watching the coronation ceremony, and longer and more complex makes with really breathtaking results.
