Hello,
Just from my personal experience during the days before using a decent camera I always scanned my coins for
ebay using an Epson WorkForce 610 scanner.
On several occasions when using this scanner I would receive comments back from the buyers that the coin that they just received from me looked better compared to the scanned photos I posted on
ebay.
IMHO one can look at this situation in two ways:
1) Scanning a coin most likely would never create a situation where the buyer would complain of receiving an inferior looking coin compared to the photos posted on-line promoting the coin.
Consequently, if one is selling low end coins it might be more prudent to scan them to lessen the chance of having to deal with time-consuming returns from dissatisfied customers.
or
2) Do not use a scanner on high end coins when particular characteristics like toning, die cracks, important scratches that lower coin values, luster, cartwheel effect etc. are desired to increase the probability that a higher and more appropriate bid price will be realized.
Plus by using a DSLR camera, for example, on these high end coins the buyer should very seldom ever complain of receiving something drastically inferior compared to the posted on-line photos...
In summary these tips just improve one's ROI (return on investment) where the investment is your precious time...
As a side note always remember that no matter which camera takes the photo always make lighting the most important criteria to dwell on.
