A set of high-magnification hand lenses is an invaluable tool for numismatists. However, magnification of 10× and up is only recommended for spotting signs of counterfeiting. Skip Fazzari offers these tips and more.
There are a host of things to see on coins. No matter what you are looking for, after a quick perusal, most collectors will seek some type of magnification to enlarge their view of the coin they are examining. I travel with an assortment of hand lenses.
There is a 20×, a 10×, and a combination 3×/4×/7×. Beginning with an overall view to address shape, color, and design, a grader will also be looking at a coin’s luster and for imperfections that detract from its eye appeal. Error/variety collectors will be looking for doubling on its design, planchet/striking problems, overdates, and overmintmarks. Authenticators will need to look more closely at its surface for die polish marks, tooling, and characteristics common to counterfeit or altered coins.
Four or five powers of magnification seem to be the norm for many collectors. At these powers, an entire coin may be viewed all at once, which is especially useful when grading. Nevertheless, unless you are an experienced numismatist, you will not be able to see characteristics such as metal flow, die doubling, and counterfeit diagnostics on many coins when using minimal magnification. The micrograph shows the head detail of a genuine 1861-O “CSA Obverse” Seated half dollar. This view is close to what you would expect to see when using a 10× hand lens.

There are many ways to collect Charlotte gold. Some people have only a mild interest in these coins and may buy just one or two pieces. Other people are more serious and they have a large number of Charlotte issues in their collection. A small number of Charlotte collectors are obsessives who focus exclusively on these pieces and do not collect anything else. I would like to make some suggestions on how to collect Charlotte gold. In my experience, all of these ideas have merit and none is “better” than the other. It depends on the tastes and budget of an individual collector to determine which one(s) is right for him.
I. THE INTRODUCTIORY THREE COIN SET
The most basic way to collect Charlotte gold is to purchase a single example of the gold dollar, quarter eagle and half eagle denominations. This is a very good way to collect for the individual who has a limited budget or who is not certain how deep his interest lies in Charlotte gold.
A basic three coin set of Charlotte gold should consist of nice, problem-free pieces. It would make sense to focus on the more common dates although some collectors might prefer to include some scarcer issues. The grade range for these coins is likely to fall in the Extremely Fine-40 to About Uncirculated-58 range.
The 1851-C is the most logical choice for the gold dollar in this set as it is the most common and affordable date. A pleasing Extremely Fine can be obtained for $1,500 or so. About Uncirculated pieces range from $1,750 to $3,500 depending on quality.
The optimum quarter eagle for this set is the 1847-C as it is the most common date of this denomination from Charlotte by a large margin. A nice Extremely Fine example costs around $2,000 while About Uncirculated coins range from $2,500 to $4,000. It is possible to upgrade to a much scarcer date without paying a substantial premium. As an example, the 1843-C Large Date sells for around the same price in Extremely Fine as does the 1847-C but it is much harder to locate. (more…)

If you have a valuable coin collection or you aspire to build one, it is imperative that you take the necessary steps to protect your coins and, ultimately, your investment. Much damage that is done through improper handling or storage of coins can not be reversed. As a result, each passing year sees fewer and fewer original, problem-free coins remaining.
The incremental cost of quality hobby supplies and tools for the proper storage and handling of one’s collection is marginal compared to the value of the coins in the collection. While there are countless products on the market that claim to offer the best protection for your coins, we have identified what we believe to be the 10 best coin protection products available today.
– One big category of coin damage we see is from staple scratches. Much of this damage comes from staples that are not completely clinched. Normal staplers leave a curl of the staple rising above the surface. This piece of staple can easily scratch adjacent coins as the coin shifts in a box or is removed or inserted from the box. Flat clinch staplers fully compress the staple into the surface of the holder leaving nothing behind to damage other coins. We like the Max HD-50DF because it is full size and uses regular staples. Max also makes half strip and palm size versions for collectors that prefer a smaller stapler. All three staplers completely clinch the staple as part of the stapling process.
– A second big category of damage type we see on coins is fingerprints. The oils and acids present on one’s hands can damage coins if left on the surface of the coin for an extended time. Initially, they can cause a fingerprint pattern toned area that is unattractive and lowers the value and grade of the coin. Left unattended, these oils and acids can eventually etch the surface of the coin making the fingerprint permanent. Even handling coins by their rims still allows the dangerous compounds onto the rims of the coins. Using a pair of soft cotton gloves when handling raw coins helps protect all three surfaces of the coins. Make sure you get a pair of thin gloves so that you can still feel the coin. Bulky “work gloves” make it harder to handle small items and increases the risk of dropping the coin.
– Metal and water do not go well together! Almost everyone intuitively knows to keep their coins from getting wet but many collectors do not realize that even the moisture present in the air (humidity) can be enough to cause damage. Silica gel absorbs moisture that makes its way inside your safe deposit box, safe or other storage area preventing it from reaching your coins and causing damage. Silica gel can be easily reactivated in the oven when it has absorbed as much moisture as it can hold. Before shopping for silica gel, measure the size of the area to be protected and then buy the appropriate size of silica gel for storage space. (more…)
