Europe and Overseas,Olympic Philately and Memorabilia - Day 2

1850, 6 Kreuzer and 6 Kreuzer just half of a stamp (both machine paper, type III)  on 1858 "Retour-Recepisse" return receipt for a registered letter from BANAT KOMLOS (scarce Hungary postmark) to Grosswardein. The entire stamp has some faults. An interesting usage showing one stamp torn in half. The certificate Sismondo (2021) calls it a rare bisect (40.000€), the Ferchenbauer cert (2023) describes it as torn by usage but mentions ”R!”.
