Trying To Sell USA Silver Coins In Mexico City & More- Help!

I would very much appreciate any help I can get in selling some USA coins.

I am a total novice trying to sell some silver coins in Mexico City. I have heard of Duane from this forum, and will contact him but am not sure he purchases these type of coins. Anyone else I should contact? Any other sales methods which you might suggest?

Does anyone know of anyone else or Mexico City coin vendors who may want to buy some or all of these?

Is it common to get a reasonable price when a person sells to a coin shop or is it likely I will get significantly less for them vs ebay.

I have about 95 silver Lincoln dimes, 20 Qtrs, and a 1972 Raised Hair ( I believe) Kennedy half dollar.

I am aware of the coin market on ebay but I am a bit concerned about the hassle of selling there when I am here and coins would need to be shipped to the USA where a friend would have to mail them out-

If I can sell them here or privately that would be ideal..

How do you send individual coins like this safely, by the way?

However, I cannot afford to take a large loss on selling these as I am selling to pay medical bills.

I am using the ebay prices shown on (124) Not Allowed - Auto-Removed as a base line for valuing each coin. Any other suggestions?

Thanks in advance, your help is greatly appreciated.
