Learned from the Past
Once in awhile we will see coins for sale in a dealer's inventory (whose inventory normally moves very quick) that we are interested in but don't pull the trigger. We check back and the coin is still there and we begin to wonder why it hasn't sold. More and more time goes by and it still has not sold. Now we don't want it because it seems no one else does!
Some years ago this happened to with a lib quarter eagle that was condition census, pcgs, and cac. Price very reasonable too. It sat for ever and I didn't buy it because of that reason even though I knew the coin checked every box. I guess I assumed something had to be wrong with it. Well it did eventually sell. That particular date never came up again in that condition or better. Then the same coin went up for auction and sold for about 50% more. It came up for auction again and went for even more. It cost the new owner more than twice what the dealer was originally selling it for. I doubt we will see that coin again for awhile.
Fast forward to now. Saw a coin on the same site that I considered buying when it was first posted but held off. Months later still there. Like before it had all the boxes checked---pcgs, cac, very rare (I doubt another date of this coin will become available in any condition in the next couple of years) and reasonable price. Didn't make the same mistake---bought it and was able to get a nice discount. Lesson learned.
