Up-Coming Hot Summer Months And Coins In The Mail

I've bought various coins through the mail over the years. Many have come during the hottest months of the year. Many of us (I do) may have roadside "metal" mailboxes. If it's 95 degrees outside in the hot sun, I'm thinking it's gotta be 120 or better in this mailbox! Not really sure how hot but it's gotta be HOT!!
I'm probably being overcautious but I don't want slabs or any coins sitting in this metal mailbox "at all" during a hot summer day. If I'm expecting coins, I'll be looking and waiting for the mail carrier or I'll have a family member waiting.
Am I being too overcautious?

You are not being overly cautious. It's good your mail box is white. The black mail boxes get really hot in the sun. Also, don't leave slabbed coins in a closed car parked in the sun.
Worry is the interest you pay on a debt you may not owe.
Excessive heat can definitely damage slabs - in cars or in mail boxes. Coins also could be affected, depending on packaging and length of time exposed. Cheers, RickO
Yes, exactly. Thank you guys for the reality check.
I wasn't really worried about the slabs themselves but you're certainly right.
Even though the slabs might be "so called" air tight, there is still air/moisture inside the slab. Going from a very HOT mailbox into an air conditioned house (or vice versa) could cause condensation. You might not see it, but it could be there.
I guess the point here is; all coins, all the time should be in a temperature controlled environment.
you might consider a P O Box
Experience the World through Numismatics...it's more than you can imagine.
Or you could air condition your mail box...
Now you went and done it. Everyone is in a tizzy and there go my summer sales.
it's crackers to slip a rozzer the dropsy in snide
Offer shipping in dry ice
If you get a box, come up with a non coin (or collectibles) related name.
Had a weird interaction the other day.
I have a small PO Box, and was looking for a couple shipments. Nothing in the box so I ask the guy sorting near the locked locker/key section.
"Yeah, aren't you are such and such. Your the guy with a drone? Yada, yada, yada"
Long story short... this box had nothing to do with my infant stage drone business... but at least he wanted to talk drones and sell me one of his expensive models.
A couple tellers know what I do. One knew I switched from a large to a small box... lol
Sometimes it can be a bit unnerving to say the least.
Never had issues with incoming mail at a USPS facility... always shipping issues down the line.

Slabbed coins in the hot sun? That’s nothing compared to fine wine being delivered in the Summer in South Florida in a dark brown UPS truck! As such, all deliveries in March and December!

Id be more worried about theft than heat
I made the mistake of ordering some chocolate candy in June in Vegas. It became one solid mess.
Once received a PCI slabbed toned ASE that had noticeably changed during shipping. It had sit in my mailbox for a few hours in the August heat. Familiar Seller had always provided accurate photos in the past. IMO, it was the heat that accelerated the toning.
