Advice for selling high volume, high quality 50’s commons and minor stars?

[Belfast1933]

I wanted to ask this group if they have any tested models or ideas that might be a good fit for a new consignment of cards that I recently picked up (I am helping a gentlemen sell his childhood collection, 1950 to 1957, mostly Topps)

The big name cards are being graded and will be available for sale in a month or so when they come back from PSA

My question - I also now have close to 1,000 high condition (ungraded) commons, heavily weighted in 1955 and 1956 Topps. I am thinking through a strategy to sell which:

1. Is efficient, not able to fill set lists one by one. Too time consuming.
2. Still drives value for the card owner, as close to “retail” value for the commons as possible, while still achieving goal 1 above.

My initial ideas are:

1. Team focused lots (no dupes) of 15-20 cards, multiple years

2. Starter sets, no dupes, maybe 50-75 cards each?

3. I have not sold on Ebay for quite awhile; but I wonder if that is a platform for higher volume, efficient selling for cards like this? (Much as I would like to help, I just can’t afford the time to sell cards one by one)

I am guessing there are some high volume sellers here too along with all of the advanced collectors - I’d value your opinions and advice.

Here are fe samples of the cards to show the quality - it’s amazing to me how well this gentlemen maintained such beautifully conditioned cards

Thanks for any ideas
