Hello and welcome to the forums. We do not value items on this site. Searching selling sites for similar items will give you an idea of what other sellers are asking. You may also research sold items on eBay. As to dry cleaning the coat, I do not see a problem if you have a reputable cleaner. Look forward to what others have to say in this regard. Is there a dated tag on the coat? I'm not seeing 30s. I will delete the other thread you started on this coat. Please know that sometimes it can take a day or two for members to respond to a query. Multiple threads for the same item creates confusion. Thanks.
The coat looks wonderful. Condition and size are two of the things that determine the value for shoppers. As Deborah says, check similar "sold" items on eBay. That's what many of us do to determine approximate value. And we LIKE getting questions about vintage Michael, so you are definitely NOT "troubling" anyone !!!
Nice coat, really like the tweed. It should not be a problem to dry clean. Definitely not 30s as the label does read Queen Elizabeth, Queen Mother and Prince of Wales. It is more likely late 50s / early 60s.
