"Say you find 8-9 examples of a rare A.C. chip that beforehand was thought to be a "one-of-a-kind" piece, and was valued at $1000+ ?
Surely your find would greatly lower the value of the existing 1 chip, and yours would not be valued at $1000 each because your find has slanted the rarity quite a bit.
Are you saying you would offer these chips to your subscribers quietly, and most likely not disclose your "find" to the general collecting public if approached on the matter?"

Good hypothetical question Justin ... and here is my hypothetical reply ... followed up with an actual experience.

First of all ... hypothetically speaking ... a unique one-of-a-kind A.C. casino chip would probably be worth several thousand dollars. If 8 or 9 showed up, of course the value would be deflated somewhat, but not drastically. The 8 or 9 pieces that you hypothetically created, might still be a $1000+ chip due to demand.

If I came across these hypothetically 8 or 9 (previously unique) pieces ... the question remains is how much am I willing to pay for them ... and how much to sell them for ... which again to be blunt, is strictly my business. I could probably sell them directly to 8 or 9 of my standing customers at $1,000 each ... and the original value would be diminished to that level ... but certainly are not worthless.

Would I disclose that there were now 8 or 9 pieces of this previously one-of-a-kind rare chip.? Of course I would ... in my catalog and among my subscribers and the adjusted price estimate would reflect that fact.

I recently discoverd just this past year a previously unknown Babbettes $100 chip from Atlantic City. I purchased five of them. That chip was sold to my customers at the same fixed price ... and they were happy to get them. All 185 of my Atlantic City Mr. Chips, Inc. new issues subscribers knew about the find which was published in my monthly A.C. e-newsletter.
