A collection falls apart into a pile of metal easily
An inherited collection has two layers of value. The first is material and cannot be spoilt. The second — the arrangement, the completeness of sets, the documentation, the previous owner's notes — is fragile and disappears with the first sort into „gold and silver". Yet on seriously built collections that second layer holds a substantial part of the price.
Hence the first piece of advice: do not split it and do not reorder it. Even if an album looks chaotic, its sequence may make sense. And an unremarkable copper coin in it can be worth more than the heavy silver thaler beside it.
How to handle coins
Most heirs do not know this, and it cannot be undone:
- Hold a coin by its edge, between thumb and forefinger. Never by the face.
- Do not touch the surface with your fingers. A fingerprint carries salt and oils that etch into the surface over time. On a coin in perfect condition that is a real loss of value.
- Do not take coins out of capsules, sets or albums. If a coin is in a capsule, there is a reason for it.
- Do not stack coins or tip them into a single box. Gold and silver are soft, and rubbing against each other creates scratches.
- Do not breathe closely over a coin while examining it — moisture carries the same risk as fingerprints.
And of course: clean nothing. Why patina is value rather than dirt is explained in Old coins: value and buying price.
How to transport a collection
Carry albums and cases flat, not upright — coins in vertical pages shift and abrade. Leave loose coins in whatever holds them, and pad any empty space in the box with something soft so nothing slides about. Do not leave a collection in a car, least of all overnight.
Before anything leaves the house, photograph the whole — albums, cases and boxes together, plus detail shots of representative pieces, obverse and reverse. This is not distrust but ordinary record-keeping: with several hundred items, nobody recalls precisely what was where a week later.
When there are several owners
With an estate, settle ownership before selling. Until probate concludes, or until the heirs agree, it is not clear who is entitled to sell the collection — and arguing about it afterwards is unpleasant for everyone.
Where there are several heirs, it is worth coming to the valuation together or agreeing in writing beforehand who acts. If you need formal documentation for a notary, check with them in advance which type is required — the difference is covered in Jewellery valuation versus expert report.
How a collection is valued
A fair valuation never comes from multiplying total weight by a single rate. The collection is first divided according to what determines value in each group:
| Part of the collection | What is checked | What can raise value |
|---|---|---|
| Bullion coins | authenticity, metal, purity, weight | current rate, liquidity, original packaging |
| Historic and collector coins | year, mint, variety, condition, authenticity | rarity, low mintage, preservation, demand |
| Commemoratives and sets | completeness, condition, documentation | complete series, certificate, original case |
| Ordinary silver and gold coins | precious metal content and condition | collector premium above metal value |
Only then are year, variety and condition assessed on the interesting pieces. On the more valuable coins, insist they be assessed individually.
All at once, or in parts?
There is no universal rule. Complete sets, thematic collections and well-documented holdings are usually better kept together, because their value lies in completeness. Bullion coins and individual rarities, by contrast, can be valued separately. Deciding about splitting only makes sense after the first assessment — before that you do not know what belongs with what.
What to watch out for
- An offer for the whole box. A single figure for an unexamined collection is almost always to the seller's disadvantage.
- Valuation at one rate per gram. With numismatics that means collector value is not being counted at all.
- A final offer from photographs alone. Photos serve for orientation and arranging a time, not for a binding valuation.
- Pressure to decide immediately. With a collection built over decades, there is no reason to rush one afternoon.
