Silent auction items: what actually sells.

The single most common mistake is having too many lots. It feels generous. It is the reason everything sells cheaply.

A silent auction works on competitive tension. Two people wanting the same thing is what drives a price up. Split the same fifty interested bidders across forty lots and almost nothing gets a second bid.

Spread the price points, not the categories

Charities tend to sort lots by type — travel, experiences, sport, beauty. Guests do not shop that way. They shop by what they are prepared to spend. For a room of two hundred, something like:

Final value	Share of lots	Why
£30–£75	~30%	Entry point. Gets first-time bidders bidding at all.
£75–£200	~40%	The engine. Most of your money lives here.
£200–£500	~20%	Competitive lots for engaged bidders.
£500+	~10%	Two or three showpieces. Not more.

If everything in the room is a £400 lot, most guests never bid once.

What reliably attracts bids

Things that are hard to get, not things that are expensive. Scarcity beats price. A table at a restaurant with a three-month waiting list outperforms a more costly meal anyone can book tonight.

Local and personal. People bid on things they recognise. A weekend at a supporter’s cottage in a place the room knows will beat a generic hotel break.

Experiences over objects. Objects have a checkable price. Experiences do not, which is exactly why they climb further.

Lots with an obvious buyer in the room. Before including anything, name the person at the event most likely to want it. If you cannot name one, it is probably filler.

Things connected to your cause. They bid on the lot and the mission at the same time, and nobody else could have offered it.

What sits untouched

• Generic gift baskets and hampers of assorted items
• Anything with a printed RRP the room can beat online
• Highly specific hobby items with no matching bidder present
• Vouchers with awkward restrictions or short expiry dates
• Multiples of the same thing

Setting the starting bid

Around 30–40% of the item’s real value.

A high opening price feels like protection. It is the most common reason a lot attracts no bids at all. Nobody wants to make the first move at a number that already feels like the ceiling. Bidders talk themselves upward from a low start and almost never from a high one.

Set increments at roughly 10% of the current bid: enough that the price climbs, small enough that nobody is priced out in a single jump.

Do you need a reserve?

Usually not, on donated lots. A reserve protects a supplier’s margin, and on a donated lot there is no supplier to protect. An unsold lot raises nothing at all; a lot sold under its value still raises money the charity did not have.
