I have communicated with another classic Thai coin collector on this board about the perils of buying raw Thai coins, if you hope for problem-free grades.
I have never sent them any raw Thai coins before, but took a shot on some Ebay auctions over the last few months. If the Rama 7 (smaller one bottom right) or one of the Rama 5
coins comes back MS anything (besides the MS61 PCGS breakout you see in there), this will have all been worth it.
Among the Rama V bahts (the one you see seven of), there are a few scarce dates. The usual Rama 5 baht has no date and is attributed to 1876-1900.
But starting in 1901 or 1902 they have "RS" numbers dating them to 1902, 03, 04, 05, 06, and 07. The PCGS breakout is a 1906.
There's also a 1905 and two 1903's in there.
The chubbier-looking guy, facing right, is Rama 6, and these are both common 1916 bahts. The bright one has some surface hairlines, I'm afraid, when turned.
These are not worth much more than the $20 grading fee, but, they could make a good gift. I'll post what the results are in a few months.
