I have multiple silver glossys, base, and base minis to trade for a black border mini or a gold border mini if anyone is interested. US only. I also have tons of other sports cards and original pokemon as well if anyone is interested in trading. I also have roughly 40ish cryptocards in total I would like to grade if anyone would like to get in with me to reach the 100 card min price break with PSA. 
I sent you a PM with an offer. Combining cards is ok of course until we have the same card being graded and then we can't tell whose card is whose. But, if there is a way to do it, i might think about it.
Just gently snip off the corner of one of the cards. Ez solution.
Lol that sounds like a reasonable solution. Maybe call PSA to see if you can send 2 separate packages and keep them aggravated between lots, although I dont think that will work probably the only solution if the cards are uniquely marked unfortunately
Could you group the cards in lots in numbered bags and adding a note asking they grade the bags in numerical order?
You would know the amount and group based on the serial number they receive once graded
Would that work? I am not 100% sure of how the grade their cards.....
