Should I remove stamps from envelopes?
A Gustamps tip to novice stamp collectors is if you have an envelope with an old stamp on it, check out if it is worth more on the envelope or cover. Gustamps point out that depending on the stamp or postmark the value might be much more if left on the original cover. Gustamps would be pleased to look at any stamps or covers you may have and give you their expert opinion and valuation free of charge.
