If you have drug addicts in your family and these are the folks that you talked about coming around you can kiss your coins goodbye right now. I am not kidding, they will fimd them and either pawn them or coin star them or spend them face value. No use hiding them. Where there's a will there is a way. You must come up with another plan. IMO
Sorry man, but I'm not buying this post at all. 1. You bought a Morgan worth $60-$80 for $1? Sure you did. And now you want to sell it. Don't try it here; even those who think you're for real won't fall for it. 2. Renters insurance pays based on the value of your belongings; not what you paid for them. Who told you different? And I was a property and casualty agent, licensed in nine states, for five years. I don't mean to be rude, but this post screams scam to me. I hope I'm wrong.
Definitely re-read the policy, you will probably find that up to $720 in silver would cover silverware, tea services etc, but not coins. Coins typically have to have their own specific rider that covers them, and the rates for those riders are high and usually require you to jump through a lot of hoops and record keeping.
I don't think your being rude, I do not blame you for being skeptical, as a matter a fact more people should be more skeptical and not so trusting this day in age you can never be quite sure. I have to go back a year or so on many ebay purchases but I will make a post on a new thread with a few of the good deals with proof. I already sold the lot of coins on here, going to the post office in a few hours to drop it off. https://www.cointalk.com/threads/selling-large-lot-of-coins-sets-really-cheap-i-am-moving.335656/ I think there was only 2-3 coins in that lot that I got a good deal but I lost a few hundred in this, I decided to keep the good deals mostly.
I will be busy today but I will try later tonight to look for the morgan I paid $1 for worth about $60-$80 but in the mean time, here are some good deals I got, you can find some of the items in the coin lot I just sold and linked in prev reply. https://www.cointalk.com/threads/some-good-ebay-purchases.335693/
I think you should get the smallest safe deposit box you can, put the stuff in there that will fit and you don't want to part with. Then sell off the rest, part of the proceeds from which will pay for the SDB.
I do not know much about renter's insurance, to be honest I did not go much into it when I bought it, I thought they only pay you for what you have receipts for, my apologizes. I pay $5 a month from lemonade.com.
You should seriously consider selling the other 70%. There may be mitigating factors you haven't shared with us, but generally speaking someone who has no job and no savings has no business tying up their assets in a hobby. Get a job and use the coins to start building an emergency cash reserve. You can always return to collecting when circumstances improve. I don't mean to sound harsh and you're certainly to be applauded for your commitment to your mother, but perhaps now it's time to focus on getting your financial life in order. Good luck!
$5 per month is probably fair for a policy up to around $10,000. Renter's insurance isn't very expensive. You should provide a list of valuables to the company, though, in case you ever do have to file a claim. For a small policy they probably won't require it, but at least have a list somewhere separate from your home, like online somewhere, so if you do ever file a claim you can itemize your losses.
