This may be an OpenSSL issue, as I connect successfully in local tests.
However, your site does not accept MSIE ciphers and just closes connection:

$openssl s_client -connect donate.mercycorps.org:443 -ssl3 -cipher RC4-RSA:RC4-MD5:DES-CBC3-SHA -debug
CONNECTED(00000003)

In nginx error_log level there should be errors about "no shared ciphers".

You may try to comment out the directive:
    ssl_prefer_server_ciphers   on;
