Proof coins are specially crafted for collectors, not intended for circulation, and possess distinct visual characteristics due to their unique minting process.
Here’s how to identify a proof coin:
Proof coins have distinct visual characteristics that set them apart from regular coins.
- Mirror-like fields: The background of a proof coin is typically highly polished, creating a reflective, mirror-like surface.
- Frosted devices: The raised design elements (devices) often have a frosted or matte finish, providing a contrast to the mirrored fields.
- Sharp details: Due to multiple striking during production, proof coins exhibit exceptionally sharp details and well-defined edges.
- Limited production and packaging: Proof coins are generally produced in smaller quantities and are often enclosed in protective packaging to maintain their finish.
- Potential certificate of authenticity: Some proof coins may come with a certificate of authenticity.
In summary, key indicators of a proof coin include a mirror-like background contrasting with frosted design elements, and sharp, intricate details.
How do I know if my coin is proof?
Appearance. Proof coins are struck twice instead of just once like regular coins, but this one extra strike gives the coins a much shinier, clean-looking finish and makes the intricate details of the design pop.
Do all proof coins have an S on them?
Proof sets were once again produced also, with production of proof coins being taken over by the San Francisco Mint. Therefore, most post-1968 proof coins feature the S mint mark (error coins that lack the mint mark exist, and some special edition proof coins were produced by the Philadelphia and West Point Mints).
How to check if a coin is silver proof?
Thanks for asking. Silver is non-magnetic, so it will not be attracted to a magnet. Despite this, there is slight resistance when gently sliding a magnet down a straight and smooth silver bar. The resistance only happens with straight smooth items however. This resistance, coupled with non-attraction, indicate the presence of silver.
