Question: Thank
you for sending me your beautiful auction catalogs. Your descriptions are very
informative but I have a question on some of your abbreviations. What does OGH
and OH mean? –A.B.
Answer: We
are happy you enjoy our catalogs. OGH stands for “Old Green Holder” and OH
stands for “Old Holder.” Over the years
the third party grading services PCGS and NGC have changed the plastic “slabs”
the coins are encapsulated in. In the first few generations of PCGS holder the
paper insert that listed the coin’s date, grade, denomination, and serial
number was green as compared to the blue insert they use today. The old NGC
slabs were thicker and had a smaller hologram on the reverse of the slab. We use this notation in our catalogs to
indicate to potential bidders when the coins were graded.
