I’ve never had that happen at Edinburgh tbh, but if you feel safer set when it comes back. I usually patina when they come back but then I don’t oxidise the mark usually and keep the backs of everything clean.If you read the blurb you have to mark where you want the mark. Are you doing your own or sending the punch in? I’m having to do a 24 hr turnaround as they have got unusually busy with businesses starting up again that I wouldn’t have got them back in time
