About 10 years, unless it's poorly made, you get unlucky or you store it near a source of ionizing radiation. Wrapping it in a couple of layers of tinfoil will help somewhat. Lead is much better. Internal batteries and capacitors are a bigger risk. They can leak in just a few years and ruin your day.

Generally, I wouldn't feel comfortable haiving a single point of failure protecting any significant value. Backup your seed phrases and dirivation paths and consider multi-sig.
