I think you are right to hesitate after having posted the Sc 24.
Your certified stamps will, as Rogdcam says, give prospective buyers some confidence that what you are selling is the real deal.
Before going to far with posting groups or individual items on eBay
, I would suggest developing a strategy. It seems you, and perhaps others in your family, are willing to put some time into sale of the collection and would prefer to maximize the dollar value you can extract from it, rather than sell it off immediately.
If anyone in your family knew a stamp collector, he or she might suggest how to divide the accumulation and approach things. Not an appraisal, and not for them to take it off your hands, but a quick consult. Two hours of on-site advice would really help you, I think.
Meanwhile, as for remote advice from SCF folks, I will pitch my 2 cents worth. I think you will want to create several categories that become tranches for sale in different ways suited to the material and market, and with different amounts of labor devoted to these respective tranches.
It could be that 80% of the dollar value is in 10% of the accumulation and that could well be the individual certified items.
Those particular individual items are worth slowing down, identifying a probable market value as seen in eBay
past sales or on Hipstamp which is an online stamp marketplace with some overlap to eBay
. For example, your used #24, with a certificate, shows a wide range of asking prices on Hipstamp, from a knock-down at $39 up to several in the $200 to $500 range which are distinguished by condition and centering.
I mention this only to suggest that certified items are likely worth individual attention. They can form a readily identified category and you can put each of them on eBay
with appropriate expectations for each individual lot. Some will only be worth a few dollars, others perhaps a hundred or more.... The unstamped letter would be among this category as a postal history item. With a cert, it will sell.
The US sheets from the 30s/40s to date might seem like a lot of stamps, and a lot of value, but as folks are saying, with few exceptions (stamps with face value of say $0.50 and over) these sheets are not worth much in today's marketplace. They can be a real hassle to sell and ship without damage to the sheet. You could
try to list the sheets one by one on eBay
, starting at face value plus shipping, or the most recent sold-at value plus shipping, but you will be at it a long, long time. I suspect if you group them, you will get dealers/resellers who only go for 50% of face or less on most of them. But there would be less hassle and work for you to monetize them....
You also have some other categories of material which would have discrete approaches, for instance the Netherlands album. If that is all contained in one or two albums, I suppose you could offer it on eBay
with many scans of the pages involved.
I hope this helps.
You have my sympathies on several counts.
