Can't think of any reason why the results can't be posted immediately; someone obviously enters the hammer price into a database somewhere. At the very least it should be released after close of play on the day. Plenty of other auction houses can do this.
You assume correctly! Love the toning on yours. As the saying goes, "they don't make 'em like they used to". Imagine this design on the inner of a £2 coin instead of the 'tat for tat's sake' stuff we get?
