KenJo Gem Coins welcomes you to our online store located on the world wide web since 1999. We offer Modern Deep Cameo Gem quality Proof Single coins and Brilliant Uncirculated business strike coins for the United States' coin collector in all series from Lincoln Cents to Presidential Dollars.

Simply scroll down the page to access the inventory.

Since it seems the 'collector preference pendulum' has swung from blast white untoned Proof coins to Proof coins with original surfaces exhibiting patina toned to various hues and differing levels of luster from dull to spectacular, we will add Proof singles to this category as we come across specimens having these characteristics.
