My 2 cents as a novice stamp collector in regards to
ebay and auction houses.
ebay is becoming full of flea market bottom feeders who want everything for nothing, and sellers who want the world for garbage.
Many big sellers as you call them inflate their prices and use shill bidders (you can argue all you want)
They use fixed price to get rid of the bottom feeders who want stuff at 5% to 10% of catalog or less.
Auction houses also price a lot of stock at very high percentages of catalog as much of it is their own merchandise. They don't start stuff at the bottom either for good reason, it will attract all the bottom feeders.
I buy very little on
ebay any more as I got tired of having to return stuff and getting a lot of the garbage sellers are selling that is totally not what was listed.
I used to buy around $10,000 per year and now down to a few supplies. If I can get it for about the same price from other than
ebay, I prefer to do that.
Everyone talks about a % of CV but what is the actual CV value today. As stated, no 2 dealers can agree and none of the catalogs can agree.
What I call lower end will always be lower end and will never change. Once everyone has those items that collect, there will be very little market for them. That is a lot of what is being sold on
ebay.
Many older collectors or their Executors in the estate are dumping on the market and very few new collectors are coming into the buying market.
Stamps that are better value and clean VF with no faults will always sell for 50% of book or more and many times way over book as there is a demand from serious collectors.
Stuff that is low grade and/or has faults will very seldom bring over 10% book unless is is scarce.
OK, done for now, lets get the whips out and have some feedback and further discussion
