So usually the coin sits in the mailbox for no more than 5 - 10 minutes. I'm with you. I'm also tracking the shipments and pretty much know when the package is out for delivery. I also have a goldfish pond in the backyard.  |

Fortunately, our mailbox at the road is in shade almost 24/7. The highs this next week stretch to 104°F. Quote:
The front of the house gets direct sun for most of the day. On these 95+ degree summer days, I'm afraid to think what the temperature might get to inside that box! I wouldn't be surprised if the temp in the mailbox approached or surpassed 130°. I suppose you could stick a small thermometer in there and find out. I don't think much harm will be done in the short term. As long as it is brought inside the same day and acclimated properly (as TNG said), I don't see many issues arising.

Do not put a baggie with tropical fish in your mailbox tho.  Actually, we don't know if the mail truck carrier had your packages sitting in a basket with the sun blazing on it through the windshield either for three hours. We really have little control over what a package goes through on the way to our mailbox. I have a remote digital temp thing on the porch that we probably picked up at Harbor Freight that tells us the temp outside on a receiver in the house. I could easily take it out and put it in the mailbox and see what the temp is inside of it. |

Interesting the care and concern the packages are given during the last hour or less of their journey. Just imagine all the transitions your items go through as the travel across the country. Going from the frozen belly of a jet at 30,000ft to a 100+ degree tarmac and then whatever happens locally.

spruett001, TNG, nfine, all excellent points! Guys like us are obviously proactive with our coins.
You can take it to the bank, that there are guys out there (probably not on this forum) that buy coins through the mail and the coins are sitting in their mailboxes throughout the country for hours or even days as we speak.

Coins won't care about ambient temps around 10% of their metal's melting point. I'd be more worried about the packaging, especially if the sender managed to get adhesive into a position where it could melt onto the coin and/or outgassing be a problem.
For anyone but the most rural of rural customers, there are many good reasons to justify the cost of a PO Box. This is one of them.

I've had coins sit in my mailbox for 7 hours without much worry other than security. Oh, and I haven't had one melt yet... Quote:
The highs this next week stretch to 104°F. I'm looking forward to this.  I've about given up on trying to keep my garden alive and this stretch we're looking at will take it's toll I'm sure. Anybody else in the south enjoying the round 2 of Sahara Desert dust?  |

1. Get an Air Conditioned mail box
2. Use a Post Office Box
3. Change any metal mail boxes to a plastic one.
4. Make your own mail box out of wood.
5. Get a job with the place that delivers your coins so you can get them first.
6. Stop buying coins via the mail system.

7. Tell the sellers (on auctions, ebay, on-line shopping, the Mint, coins you're having graded via TPG'ers, etc..) you will pick them up!  Edited by USSID18

8. Or just ask for a refund on ebay, if the coins get destroyed in the mailbox from the temperature and blame it on the seller. Then click the reason why you're wanting a refund and put "Item Not As Described". Errers and Varietys.

I soak my coins in my fish tank to equilibrate them before opening. With all the tape some of you use, the packages usually float.

Coins won't care about ambient temps around 10% of their metal's melting point. I'd be more worried about the packaging, I agree. I haven't done the experiments, but generally speaking the rate of chemical reactions doubles for each 20 degrees F. So, if a coin sits in a hot mailbox for a day, you would expect that surface reactions like toning would speed up a bit for that time. 8 hours at 150 F would come out to being equivalent to a week of time at normal room temperature. If the coin is in a plasticized PVC flip, we are talking about something different: the rate of migration of the plasticizer out of the plastic (not a chemical reaction). Temperature will also speed up this process, but not sure by how much. By the way, all plastics (even polyethylene) have additives that will slowly migrate out to the surface of the plastic (it's why you are able to easily unscrew the top off of a bottle of soda). But some have more than others. |
