It is indeed a large amount of material and something that many folks here familiar with, many of us have entire rooms full of material. But volume, and often even age, is not what determines value. As you are finding out, the amount of work and man-hours is huge.
Here are your options as I see it;
- If anyone in your family has any interest, you have a great start on a new hobby; they will be able to spend months coming up to speed and learning.
- If the desire is to sell this material off a maximum value, then someone in your family will need to spend many weeks coming up to speed and learning. Then more time would be needed to image and list many smaller lots on eBay
(note that eBay
and the postal system will probably make as much as you do).
- If the desire is to sell this material quickly and without weeks of time invested, sell it as single lot at a discount
- If the desire is to sell this material quickly and without any time invested, sell it to a reseller/dealer at a deep discount
