Coins

Balboa coinage from the 1904 Panama pill onward:

is where most local collections start. The first republican series was struck in silver at the Philadelphia mint, and its smallest coin was so tiny that collectors nicknamed it the Panama pill. From the 1930s the tenth, the quarter and the half balboa and the big one-balboa crown carried Balboa in his helmet, and they stayed 90 per cent silver until the mid-sixties, when the smaller coins went over to copper-nickel and the half balboa to a weaker silver alloy for a few more years. After them come the circulating commemoratives: the coloured canal quarters struck in Canada, the World Youth Day balboas and the bicentenary pieces, which many people set aside from their change. Gold and silver pieces struck for collectors rather than for circulation form a series of their own. Old silver and gold that ended up mounted in jewellery is usually judged as antiques, and anyone used to graded trading cards will recognise the sealed-slab logic that runs the top end of coins.

How much grade a coin collection needs:

depends on what it is for. A buyer stacking silver cares about fineness and weight and will pay as readily for a worn crown as for a sharp one. A collector filling a run of dates pays for the date and above all for the condition, and the difference between a coin that passed from hand to hand for decades and one that never left the bank roll is the whole game. For anything expensive, a coin sealed and graded by NGC or PCGS saves an argument about condition; a set of commemoratives from change needs nothing more than an album or the original folder.

The silver floor under a pre-1966 balboa:

is where any price starts. Each of those coins is worth at least the silver in it, and silver moves every day, so look up the spot price before you name a figure. Above that floor, date and wear do the work: a one-balboa crown from the 1930s or 1940s goes for around $70 with honest wear and $150 or more if it never circulated, while a coloured canal quarter or a Youth Day balboa saved from change rarely fetches more than a dollar or two above face, because each was struck for everyday use.

The weight stamped on the coin itself:

is the first test of a Panamanian silver piece. The older coins carry their fineness and their weight in grams on the face, so a jeweller’s scale and a caliper settle a lot: cast copies tend to come in light, with soft lettering, a grainy surface or a faint seam around the edge. Silver is not magnetic, so a coin that jumps to a magnet is out. Tilt the coin under a lamp to look for cleaning, which leaves fine parallel hairlines and a flat, too-bright shine that collectors mark down hard. Coins that spent years hanging from a chain show a solder spot or a filed rim. And check the certificate number of a slabbed coin on the grader’s own website, because counterfeit slabs exist too.

Coin photos taken in daylight, without flash:

let a buyer judge the wear before agreeing to meet. Shoot both sides and the edge on a plain background, hold coins by the rim and leave them as they are, with no polish and no dip. Give the date, the denomination, the weight if you have a scale, and whether the piece came out of circulation, a sealed set or an inheritance. A serious buyer will arrive with a loupe and a pocket scale and expect to use both. A jar of commemorative canal quarters sells best sorted into complete designs first, since a collector pays for the coin missing from the album, not for a dozen of the same one.
