Sed usage to eliminate characters around certain patterns but not others

I have a file with thousands of lines marked similar to this:

{3203}

{1293}

{xii}

{xi}

{vii}

etc...

I need to eliminate the brackets around the numbers but not the letters (roman numerals) so in essence it would look like

3203

1293

{xii}

{xi}

{vii}

etc..

I would put up what I've been testing so far, but I'm not especially close to getting any part of the sed statement correct.

Couldn't get it to work with sed, but this works if you have Perl available:

perl -pe 's/{(\d+)}/\1/' inputfile

This might be close to what you are looking for:

sed -e 's/{\([0-9]\+\)}/\1/g' inputfile
