Antique Coin Handling Manual

—For those who own antique coins not in slab cases—

Out of a desire to keep their antique coins as clean as possible,
some people occasionally wipe them with soft cloths or polish them using chemicals.

However, this is a maintenance method that should be avoided as much as possible for both antique and modern coins.

Even if you intend to wipe them with a soft cloth,
you may cause invisible, fine scratches that could lower the value of the coin.

Furthermore, touching them with bare hands leaves behind finger oils,
which can cause oxidation and other changes to the coin's surface.

In the past, some people used to say that "if a coin rings when tapped, it is genuine,"
but that is now considered a complete taboo.

To protect coins not in slab cases

If your coins are not in a dedicated "slab case",
please pay attention to the following points:
• Avoid friction from chemicals or cloths
• Do not touch with bare hands
• Avoid direct sunlight, high temperatures, and high humidity
• Establish a secure storage environment

In particular, to protect your valuable tangible assets from the risk of fire,
we recommend storing them in a fireproof safe.

One coin collector,
anticipating "how long their home might continue to burn in the event of a fire,"
chose a safe capable of withstanding that duration.

We also heard a story about how they bought reinforcement materials for the closet where the safe would be placed at a home improvement store with their son,
and even installed it themselves as a DIY project.

Protecting coins means protecting memories and history

Coins that are protected alongside reliable family members are surely happy.
And those coins, too, are likely ticking away time quietly in the hands of their owners.
