ebay account. Understood that the highest returns come from selling in pieces, but I lack the patience for the drama that apparently comes with maintaining an
ebay platform.
Response: I recommend that you give
ebay a try. You are still young and have the time, and you might find that it can be fun.
You will need to develop finesse in scanning multiple stamps (lots) at once. Try to have great images. If you are new to this, developing speed with images will take a few weeks.
It will take some patience to get used to using
ebay's template feature for creating a listing. An experienced friend would accelerate your learning how to use templates, and how to make nice images. Learn how to use the
ebay template feature. You will get faster using templates as the weeks pass.
Scan and picture both sides of stamps. Try maybe a dozen lots per week for two or three weeks and see if you like the results.
Price stamps or sets at a generous discount but at a level you can live with. For most lots, you will have two, one, or no bidders. There is a lot of competition out there.
ebay will give you dozens of free listings per month. You would pays fees only when a lot sells. Fees are subtracted from your sales prices and postage.
At first, or perhaps longer, sell only to United States addresses, nowhere else, although some foreign bidders will ignore this and bid anyway. If they buy, mail the lot and charge them foreign postage. Selling to USA only will simplify your postage costs. Pack and ship right away, the next day, so you develop a reputation for a fast shipper. Get sold lots into your mailbox for pickup, before your carrier gets there. Driving to the post office can become a drag.
I always charge minimal postage ($1.50) and make sure that any stamp lot fit into a No. 6¾ size envelope. Use some stiffener, perhaps not thicker than cereal box cardboard, and a glassine hung on the cardboard with a small piece of adhesive tape. Do not overtape: layers of tape will annoy some buyers. Use Priority Mail or other special services for valuable lots, value to be determined by you. I never include an invoice (to minimize my work), and no one has ever complained, buy I always write "Thank you" somewhere inside the mailing and sign it.
With great images and correct description of stamps and any faults, with that description being in words, I have had almost no buyer drama, maybe two returns per 400 sales when selling my pre-1940 United States stamps. Be honest with descriptions. Use words rather than tell potential buyers to look at your images for any details they should know.
