If you handle probate work, you'll have hit this before. Somewhere in the estate there's a loft, a garage or a spare room full of comics, and nobody involved, not the executor, not the family, sometimes not even the house clearance firm, has any real way of knowing whether it's worth £50 or £5,000. That uncertainty is exactly where estates get exposed, either to an HMRC enquiry for undervaluing a genuine collection, or to an executor paying for a specialist valuation that was never really needed.
What HMRC actually requires
The standard here is open market value at the date of death, not what the items cost originally, not an insurance replacement figure, and not a guess based on nostalgia. It's the price the collection would realistically fetch between a willing buyer and a willing seller, on the open market, on that specific date. That's the definition that goes on Schedule IHT407, Household and Personal Goods, submitted alongside the main IHT400 return where the estate requires one.
The practical points that matter for a comic collection
Ordinary household contents can usually be estimated by the executor or covered by a general house clearance valuation. Anything that could reasonably be worth more than around £1,500 as an individual item or a distinct collection is the convention most practitioners use as the point to bring in a specialist instead.
Comic collections fall squarely into the "collections" category HMRC's own IHT407 guidance flags separately from general contents, precisely because a non-specialist has no reliable way to value them.
HMRC's own internal guidance points toward a valuer with genuine trading experience in the specific asset type, someone who actually buys and sells that category of item professionally, rather than a generalist.
A genuine post-death sale, particularly one achieved on the open market, is treated as strong evidence of open market value in its own right, sometimes stronger than a desk valuation.
Valuation is assessed at the date of death specifically. If there's a gap between the death and when I'm asked to look at the collection, that's noted and accounted for rather than ignored.
Why a general clearance valuation usually isn't enough here
A house clearance company sees an enormous volume of ordinary household goods and can give a fair, defensible estimate for most of it in minutes. Comics aren't like the rest of that inventory. A box of a hundred ordinary 1990s issues might genuinely be worth very little, while the box sitting next to it could contain a single key issue worth more than everything else in the loft combined, and there's no way to tell the difference without knowing the market. I've seen genuine keys sitting unnoticed in boxes that looked, to anyone who doesn't do this daily, like nothing worth a second glance.
That cuts both ways. A collection can be quietly undervalued and left off a schedule it should have been on, which is a real exposure for the executor if HMRC later queries it. Or it gets wildly overvalued using nostalgia or a handful of eBay listing prices for the rarest issue in a run, rather than what the whole collection would genuinely fetch on the open market, which risks the estate overpaying tax on a number that was never realistic. Both mistakes are avoidable with a proper look from someone who actually trades in this specific market.
What I actually provide
I'm not a RICS-accredited valuer, and I won't pretend to be one. What I am is a working comic dealer who buys and sells collections every week, which is precisely the kind of specialist HMRC's own guidance points executors toward for a category like this, someone with genuine, current trading experience in the relevant market, rather than a generalist making an educated guess.
A written valuation
A clear, itemised note of what the collection contains and its realistic open market value, something you can put straight in the file.
Date of death accounted for
Where there's a gap between the date of death and when I look at the collection, I'll note that and value accordingly rather than just using today's figures.
An outright purchase option
If the estate simply wants the collection liquidated rather than valued and distributed, I can make a fair cash offer for the whole lot and the sale proceeds themselves stand as evidence of open market value.
No guesswork
Every figure is based on what I'm actually seeing sell in the current market, not insurance-style estimates or replacement values.
If this comes up more than occasionally
If comic or collectible estates come across your desk with any regularity, it's worth having someone you can call without starting the conversation from scratch each time. I'd rather be a standing contact for this specific asset type than a one-off search result, and a working relationship means faster turnaround for you on every future matter.
