Big, flashy coins dominate coin news. The bigger the better. Large, color photos of gold and silver coins get all the publicity.
Small coins can be beautiful too. There are many scarce and desirable coins that are tiny.
Gold dollars were among the smallest coins issued. Even a non-mint state coin looks pretty. Uncirculated and proof coins are little gems, with the proofs resembling jewels. How many of these coins have survived being melted, lost, or otherwise mistreated? As for history, try the 1861-D gold dollar, a coin with a story worth an entire article.
Half dimes are much neglected. Minted from 1794-1873, the general public is not aware that five-cent nickels were not coined until 1866. Little half dimes were minted. Look at the no-stars coins of 1837, or any half dime in a high grade, or a proof. Study a proof under a magnifier. Lovely coins.
And for another underrated coin, what about the three-cent silver coins of 1851-1873? Small and silver, without a Liberty figure, these coins can be attractive. Many were well-used, but quite a few exist in high grades. Some show toning in shades of blue and purple. A coin dealer once described these as "sweet little coins."
Think small. Small coins are beautiful too.
