What You Need to Know About the Queen Elizabeth II Diamond Jubilee Commemorative Collection
The Queen Elizabeth II Diamond Jubilee was marked in 2012 across the Commonwealth with a wide range of issued items, from stamps and coins to commemorative plates and medallions. If you are looking to get into collecting these or need to verify what you already have, the market is messy. There is a lot of rebranded stock being sold as "limited edition" that actually has no real provenance behind it. I spent several years cataloguing these items for a dealer, and the things I wish I had known upfront would have saved me a lot of headaches. The official issuing bodies were across the Commonwealth. The Royal Mint produced the coins. The Royal Mail handled the UK stamps. Other Commonwealth nations had their own mints and postal services producing their own versions. The one thing they all share is a date range of 2012, and nearly every one of them carries the "D·G·REG·F·D" or "ELIZABETH II" portrait by Ian Rank-Broadley, or the older Arnold Machin design. Here is the part people miss: the Jubilee year also saw the release of a massive number of third-party commemorative items that had no direct connection to the Royal Household or the government. These are the ones that clutter up auction sites and thrift stores. I ran into a specific problem with a batch of so-called "Diamond Jubilee silver proof medals" that a supplier brought in. They looked legitimate at first glance — heavy, beautifully packaged, numbered editions. But the hallmarking was off. The "925" stamp was too shallow and the lettering was slightly wrong. The supplier didn't know the difference between the Royal Mint's official Jubilee medal releases and these third-party reproductions. My workaround was to check against the Royal Mint's published Jubilee catalogue and then cross-reference the serial numbers. Official Royal Mint pieces have traceable numbering. Anything without a verifiable serial fell into the "third-party commemorative" bucket, which carries far less resale value.
The Coins and What to Actually Look For
The Royal Mint issued a dedicated Diamond Jubilee coin series. These include the Crown, the Half Crown, the Five Pound piece, and the standard circulating £2 coins. The key coins to know about are the ones minted in silver and gold proof quality. The silver proof Crowns are the most commonly counterfeited because they are the most desirable to casual collectors. Real ones weigh exactly 28.27 grams and measure 38.61mm in diameter. Fakes tend to be slightly lighter and slightly smaller. I learned to carry a digital caliper and a precision scale to any coin show after buying a handful of fakes early on. Another thing nobody talks about is the condition tiering. The Royal Mint Jubilee coins were released in multiple grades: Brilliant Uncirculated, Proof, and then various premium finishes like "colourised" or "halo" editions. The colourised versions look nice on a shelf but they have zero premium in the secondary market beyond what the Royal Mint originally charged. If you are buying for investment or serious collecting, stick to the standard silver proofs. The colourised versions are essentially novelty items at this point.
The Stamps and Postal History Side
The Royal Mail issued a definitive set of Diamond Jubilee stamps, along with a special first day cover programme. The stamps feature a portrait by Martin Seeley based on the original Williamson design. These are not particularly rare in themselves. The value is usually in the First Day Covers, especially those signed by the postmaster or bearing special cancellation marks from notable locations. I once sourced a First Day Cover from Balmoral with the correct Jubilee cancellation, and it sold for about three times what a standard FDC from London would fetch. Location matters more than people realise with these items. The bigger trap here is the "commemorative envelopes" sold by private companies. These are not Royal Mail issues. They are privately produced envelopes with Jubilee-themed artwork and sometimes a real stamp glued on. They have negligible value. I see them come through the shop regularly and people get genuinely upset when I tell them they are worth face value. The trick is checking whether the stamp and envelope were issued by the Royal Mail itself or by a third-party producer. If the envelope says something like "Diamond Jubilee Commemorative" and doesn't reference the Royal Mail or Her Majesty's Post, it is a private product.

Common Pitfalls and Where This All Falls Apart
The biggest issue with collecting Jubilee memorabilia is the sheer volume of reproductions and replicas. There are factory-made replicas of the coins, the medals, and even the stamps that circulate alongside the real items. eBay and Amazon are flooded with them. The reproduction market has been growing steadily since 2012, and it shows no sign of slowing down. A good rule of thumb is that if the price looks too good to be true for a silver Jubilee coin, it almost certainly is. The silver content alone in a genuine Royal Mint proof Crown is worth a baseline amount that any reputable seller knows. Another limitation is the emotional pricing phenomenon. Because the Jubilee was such a widely covered event, a lot of people who have personal memories tied to it are willing to pay a premium. This inflates prices on items that don't actually warrant it. I have seen sets of Jubilee stamps sell for double their catalog value simply because the seller found a buyer who was emotionally attached to the year 2012. If you are buying to resell, this is a risky market because you are competing against sentiment rather than intrinsic value. If you are just starting out, I would recommend focusing on one category rather than trying to collect everything. Coins are easier to authenticate if you invest in a basic testing kit. Stamps require more knowledge of cancellations and first day covers. The third-party commemorative plates and medallions are the hardest category because the authenticity spectrum is so wide, ranging from legitimate licensed products to complete factory fakes with no clear grading standards. A British Coins Society membership or a Philatelic Society connection will give you far more practical help than any online guide ever will.
Where to Find Legitimate Sources
The Royal Mint website still lists and sells many of the original Jubilee releases, though some items are long sold out. For stamps, the Royal Mail Collectors Shop is the primary official channel. Beyond that, the main reputable dealers in the UK are firms like Whittall, James Spence, and Cherrystone. In the US, Stack's Bowers and Great Collections are reasonable starting points. Avoid any seller who doesn't provide clear return policies and authentication guarantees. The market is large enough that there are plenty of honest dealers, but the untrustworthy ones are numerous and often very convincing. If you already own items and want to verify them, the Royal Mint has a customer service line where you can provide serial numbers and get confirmation on whether a piece is part of an official release. This is the single most reliable verification method available. For stamps, the Royal Philatelic Society London offers advisory services. Both of these are free and far more useful than paying for an appraisal from a random third party.
