Unlisted 1968? Italian TB Seal

Unlisted Italian National TB Seal

Most Italian TB seals are dated in Roman numerals. This is not. Any information on this seal would be appreciated. email your webmaster, john@christmasseals.net

I'm guessing this was issued between 1968 and 1974 because Italian TB seals used a bold red border in the margin those years. A fine red border was used from 1949 thru 1956. This seal is overprinted 100 Lira, up from 10 Lira. most overprints were done the next year. 10 Lira was used from 1949 thru 1967
