Two evenings, four very different rooms. A stamps-and-coins specialist in Hertfordshire opens the same night a two-day general antiques sale kicks off in County Tyrone, and by Wednesday dawn a pair of Bonhams online sales are closing to an international audience of watch, pen and jewellery buyers. Here’s each sale, plainly — when, where, how to bid and who it suits.

What’s in the Alliance Auctions stamps, coins and postcards sale?
If a good evening means a stockbook, a magnifier and a pot of tea, this one’s for you. Alliance Auctions runs its Stamps, Coins, Postcards & Collectables sale on Tuesday 25 August 2026 at 7:00pm (BST), online and in person. It’s a mixed collectables evening — the bread and butter of philately and numismatics, plus the postcards that dealers and social historians quietly chase.
Individual lots aren’t published yet, so keep an eye on the live catalogue as it fills out. Sales like this reward patience: strong single stamps and better coins get catalogued individually, while the real value often hides in bulk lots and album accumulations. Viewing is by appointment only — phone to book, standard for a specialist working from a private address.
When and where is it?
The house sits at Little Hallingbury, near Bishop’s Stortford (CM23 9JW), on the Essex/Hertfordshire border. Register early on the platform to bid live, or leave commission bids if 7pm doesn’t suit.
Is Viewback Auctions Omagh’s two-day antiques sale worth a look?
For a proper rummage, Viewback Auctions Omagh hosts a 2 Day General Auction with Antiques across two evenings: Tuesday 25 and Wednesday 26 August 2026, both from 7:00pm (BST), online and in person. General in the best sense — antiques alongside household and decorative pieces, which is exactly where furniture buyers, interior designers and first-time bidders tend to do well.
The rooms are at Mote Cottage, Beragh, near Omagh in County Tyrone, Northern Ireland. Practicalities matter here: viewing is online or in the room from 2pm each day, and collection is Thursday and Friday, 10am–5pm. Bidding online? Everything must be collected in person or by your own carrier, so budget for transport before you talk yourself into a sideboard.
Who is it for?
Two-day general sales are the training ground for the trade. Browse the full catalogue lot by lot — brown furniture is keenly priced right now, so a decent oak or mahogany piece can undercut a modern flat-pack equivalent.
What’s in the Bonhams Luxury Online: Watches and Pens sale?
Now the shiny end of the week. Bonhams runs Luxury Online: Watches and Pens, an online-only sale closing Wednesday 26 August 2026 at 5:00am (BST) — an early finish that reflects an international bidding audience. It’s run from Bonhams’ London headquarters at 101 New Bond Street.
Watches and fountain pens make natural bedfellows: both are wearable engineering, both hold value when maker and condition line up. Wristwatch buyers should read condition notes closely — originality of dial, case and movement is where prices are won or lost — while pen collectors hunt the better limited editions and vintage nibs. Check the live catalogue for the full line-up, and remember buyer’s premium is added on top of the hammer price at Bonhams.
When is the Bonhams Online Jewellery, Hong Kong sale?
The fourth sale is a companion piece: Online Jewellery, Hong Kong from Bonhams, also online only and closing Wednesday 26 August 2026 at 5:00am (BST), catalogued from London. The Hong Kong tag tells you plenty: a market that leans towards fine gemstones, signed jewels and international taste, so expect strong global competition even at an early UK hour.
Whether you’re collecting or buying to wear, treat the descriptions as your friend — gemstone weights, certification and maker attributions all move value. It’s a sensible route to fine pieces without a live-room scrum. Browse the Hong Kong jewellery catalogue and set your maximum before bidding opens; timed online sales make it easy to chase a lot further than you meant to.
How do you bid across these four sales?
Four sales, four moods: specialist stamps and coins in Hertfordshire, a hands-on antiques hunt in Tyrone, and two polished Bonhams online sales for the watch, pen and jewellery crowd. Register in advance on each platform, read the condition reports, and factor in buyer’s premium and collection before you commit. Follow Alliance Auctions, Viewback Auctions Omagh and Bonhams on Auction Eagle to line up your autumn buying.
