Bank safe deposit box or home safe: how to protect a valuable collection
Security, access, humidity and insurance – which solution is better for your collection
BulgarianCoins editorial team 3 min read
As long as the collection is a few albums of circulation coins, the question of a safe does not arise. But after the first gold coin, the first PCGS slab or the first inheritance, it comes quickly. The two main solutions – a bank safe deposit box and a home safe – have different advantages.
Bank safe deposit box
Most large banks in Bulgaria offer individual safe deposit boxes for rent in their vault. The rent depends on the size and the bank and is paid annually.
Pros: very high physical security; the coins are not in your home; peace of mind when travelling.
Cons: access only during the branch’s opening hours; some banks require an appointment in advance; the contents are usually not insured by the bank – it is responsible for the box but does not know what is inside. You have to arrange insurance yourself.
Home safe
Pros: access at any time; you can work with the collection whenever you want; a one-off cost.
Cons: security depends on the model and installation; insurers often set requirements for the grade and anchoring; the risk of fire and flood is yours.
Comparison
| Criterion | Bank safe deposit box | Home safe |
|---|---|---|
| Security against theft | very high | depends on grade and installation |
| Access | opening hours | around the clock |
| Insurance | you arrange it | you arrange it, with requirements |
| Fire and water | protected vault | only with a fire-resistant model |
| Cost | annual rent | one-off purchase and installation |
| Suitable for | gold, rarities, inheritance | an active collection |
Many collectors combine the two: the most valuable part is in the bank, and the coins they work with are at home.
How to choose a home safe
- Resistance grade. Look for a certified grade under the European standard EN 1143-1. Insurers often specify a minimum grade for a given sum insured.
- Anchoring. A safe below a certain weight must be anchored to the floor or wall. Otherwise it can be carried away whole.
- Fire resistance. Ordinary safes protect against theft, not fire. If you want both, look for a dual certificate.
- Size. Buy a bigger one than you need now. Collections grow.
Humidity – the invisible enemy
A closed safe traps moisture, especially if it is built into a wall or in a basement. Put silica gel and a small hygrometer in it. The goal is relative humidity below 50%. We explain this in detail in Humidity, temperature and silica gel. The same applies to a bank box – take a bag of silica gel and replace it at every visit.
Inventory and photos
Wherever you keep the coins, make an inventory: coin, year, condition, a photo of both sides, purchase price. Without such an inventory, an insurer will find it hard to pay compensation, and your heirs will not know what they have. How to do it easily – in How to catalogue your collection.

Discretion
The best safe is the one nobody knows about. Do not discuss the collection on social media with details about your home, and do not post photos of the safe. See also our tips on How to display coins at home.
