Large volume submission for grading - your advice?

[Belfast1933]

I will be submitting a large volume (about 100) of cards soon to both SGC and to PSA for grading - most of these are prewar so I want to be careful about insurance, submission process, etc.

I would appreciate hearing from others when submitting larger quantities of cards for grading:

- would you send as one package or is there a benefit of breaking into smaller lots to spread the risk of loss?

- what insurance would you consider for the transport? Would hobby insurance alone (like CIS) be enough or would you also add any postal service coverage?

- and lastly, any advice of how to package the cards from the outside to limit the threat of theft or loss? I wish there was a nearby show soon where I could drop off to PSA and SGC but no such luck.

Thx for any advice on this.
